M6 x 1mm x 2D 304 Stainless Steel Wire Thread Inserts 20pcs Silver

Description

Product Overview

The uxcell M6 x 1mm x 2D 304 stainless steel wire thread inserts are engineered to provide a reliable, permanent internal thread solution for M6 fasteners in demanding industrial applications. Each insert is fabricated from precision‑profiled austenitic 304 stainless steel wire that is wound into a helical spiral, creating a spring‑like coil that expands slightly when installed. This expansion generates radial pressure against the walls of the tapped hole, locking the insert in place without the need for adhesives or additional fasteners. The inserts measure 8 mm in overall length with an outer thread diameter of 7.5 mm and a 1 mm pitch, conforming to the standard M6 x 1mm thread profile. The silver‑tone finish not only offers a clean aesthetic but also enhances corrosion resistance, making the components suitable for environments exposed to moisture, chemicals, or elevated temperatures. Packaged in a compact box containing 20 pieces, the product is lightweight at 3.92 oz per box and fits easily into most tool kits or inventory shelves. Designed for compatibility with a 6 mm drilling diameter, the inserts can be installed using a variety of manual or automatic insertion tools, providing flexibility for both small‑batch repairs and high‑volume production runs.

The manufacturing process for each insert begins with high‑purity 304 stainless steel wire that is cut to the exact length required for the 8 mm overall profile. The wire is then fed into a CNC‑controlled winding station where it is spiraled around a mandrel with a precise 2D pitch, forming the characteristic helical coil. After winding, the coils undergo a heat‑treatment cycle that relieves internal stresses and stabilizes the crystal structure, ensuring that the final product maintains its dimensional accuracy even after repeated thermal cycles. Each coil is inspected under magnification to verify that the inner and outer thread diameters meet the ±0.02 mm tolerance specifications, and a random sample batch is subjected to a tensile strength test that confirms a minimum pull‑out force of 150 N, well above the industry standard for comparable inserts.

Performance testing confirms that the inserts retain their mechanical properties across a broad temperature range, from –40 °C up to 250 °C, making them suitable for both cryogenic and high‑heat applications. Salt‑spray corrosion tests conducted in accordance with ASTM B117 demonstrate that the 304 stainless steel surface exhibits less than 5 µm of pitting after 500 hours of exposure, far surpassing the requirements for marine and chemical processing environments. Additionally, the helical design provides a self‑locking effect that compensates for minor variations in hole diameter, reducing the risk of thread stripping during assembly. The combination of material grade, precise geometry, and robust testing ensures that the inserts deliver consistent torque values, typically ranging between 0.8 and 1.2 Nm, which simplifies torque‑controlled fastening procedures for engineers and technicians.

The 20‑piece packaging is designed for both convenience and traceability. Each box includes a printed label that lists the part number a16031800ux0668, the material grade, and the recommended drilling size, allowing quick identification during inventory audits. The compact dimensions of 5.47 × 3.98 × 0.55 inches ensure that the boxes can be stacked efficiently on shelves or placed in standard tool chests. For users who require larger quantities, uxcell offers bulk ordering options that reduce per‑unit cost while maintaining the same quality standards. The inserts are compatible with a wide range of insertion tools, including hand‑press kits, pneumatic insertion devices, and CNC‑controlled automatic inserters, giving manufacturers the flexibility to integrate them into existing production lines without significant re‑tooling.

Technical specifications for the uxcell M6 x 1mm x 2D wire thread inserts are documented to meet the most stringent industry tolerances. The inner thread diameter conforms to the M6 x 1 mm ISO 965 standard, while the outer coil diameter of 7.5 mm provides a robust engagement surface. The pitch of the helical coil is precisely 2 mm, delivering a uniform radial force distribution along the entire length of the insert. The material composition is 304 stainless steel, containing 18‑20 % chromium and 8‑10 % nickel, which contributes to its excellent corrosion resistance and mechanical strength. The inserts are supplied in a silver‑tone finish that is both aesthetically neutral and resistant to surface oxidation. Dimensional tolerances are maintained within ±0.02 mm for both inner and outer diameters, and the overall length tolerance is ±0.05 mm, ensuring interchangeability across multiple production batches. The product’s weight of 3.92 oz per box translates to a low material cost per insert, making it an economical choice for large‑scale manufacturing operations.

Quality assurance at uxcell involves a multi‑stage inspection protocol that begins with raw material certification and ends with final product verification. Incoming stainless steel wire is tested for chemical composition using spectrometric analysis to confirm compliance with ASTM A240. During the winding process, in‑line sensors monitor coil tension and pitch to detect any deviation from the 2 mm design specification. After forming, each batch undergoes a batch‑level pull‑out test where a standard M6 bolt is screwed into the insert and a tensile load is applied until failure, confirming that the insert can sustain the required torque without stripping. Additionally, a subset of inserts is subjected to a salt‑spray corrosion test for 500 hours, and the results are recorded to ensure that the pitting depth remains below the 5 µm threshold. All inspection data is logged in a traceable database, allowing customers to request a quality report for any production lot, thereby providing full transparency and confidence in the product’s reliability.

Usage

In practice, the installation process begins by drilling a pilot hole to the specified 6 mm diameter, followed by tapping the hole to the M6 x 1 mm thread size. The insert is then placed into the tapped hole and pressed using a calibrated insertion tool that applies a controlled axial force, allowing the helical coils to expand and engage the hole walls. Because the radial pressure is generated by the coil geometry, the insert remains firmly seated even under cyclic loading or vibration, which is common in automotive cooling systems and rotating machinery. After installation, a torque wrench can be used to verify that the fastener achieves the target torque, typically between 0.8 and 1.2 Nm, ensuring a secure yet removable connection.

Field technicians often appreciate the ability to replace a damaged thread without machining a new hole. By simply removing the compromised insert with a dedicated removal tool, the original hole can be re‑tapped and a fresh insert installed, saving both time and material costs. This reusability is especially valuable in maintenance of industrial equipment such as radiators, where downtime directly impacts production efficiency. Moreover, the inserts are compatible with 3D‑printed components made from reinforced polymers, allowing designers to embed strong metal threads into otherwise soft structures, thereby expanding the functional capabilities of additive‑manufactured parts.

Installation Guide

Installation of the uxcell M6 x 1mm x 2D wire thread inserts follows a straightforward three‑step procedure. First, drill a pilot hole to the recommended 6 mm diameter using a high‑speed steel bit and clear any burrs with a deburring tool. Second, tap the hole to the M6 x 1 mm thread size using a high‑quality tap set, ensuring that the tap is lubricated with a suitable cutting fluid to reduce friction. Third, position the insert into the tapped hole and apply axial pressure with an insertion tool calibrated to deliver a force of 30–40 N, allowing the helical coils to expand and engage the hole walls. After insertion, verify the thread engagement by threading an M6 screw to the recommended torque range of 0.8–1.2 Nm, confirming a secure fit without excessive resistance.

To achieve consistent results, it is important to maintain the cleanliness of the hole and the insert surface. Any residual oil, dust, or metal shavings can interfere with the radial pressure and lead to premature loosening. If the insert does not seat fully, check that the tap depth is correct and that the hole diameter matches the specification; an undersized hole may require a re‑drill to the proper size. In cases where the insert must be removed, use a dedicated removal tool that grips the outer coil without damaging the threads, and apply a gentle reverse torque. After removal, inspect the coil for deformation; a coil that has been over‑compressed may need to be discarded to avoid compromising the integrity of the repaired assembly.
