Self-Tapping Inserts 20Pcs 302 by Focket Carbon Steel M2*0.4‑M4.5*0.5

Description

Product Overview

Focket’s 20‑piece self‑tapping insert kit is engineered from high‑grade carbon steel, delivering a combination of strength, durability, and precision that meets the demanding requirements of modern manufacturing and DIY projects. Each insert is sized to transition from an inner M2*0.4 thread to an outer M4.5*0.5 dimension, providing a versatile solution for a wide range of hole diameters and material thicknesses. The robust carbon‑steel composition resists corrosion, wear, and the cyclic stresses that can cause traditional fasteners to loosen over time.

Designed with a generous contact surface, these inserts distribute load evenly across the surrounding material, reducing the risk of splitting or deformation in wood, engineered plastics, and composite panels. The self‑tapping feature eliminates the need for pre‑threaded holes, allowing installers to create secure, threaded connections quickly and with minimal tooling. This efficiency translates into reduced assembly time and lower labor costs for manufacturers and hobbyists alike.

Technical specifications include a product dimension of 3.94 x 2.36 x 0.79 inches, a weight of 0.69 ounces per set, and compliance with industry standards for thread tolerance and load capacity. The kit is packaged in a compact, resealable pouch that protects the inserts from moisture and mechanical damage during storage and transport.

Usage

These inserts excel in applications where a reliable, reusable thread is required within wooden substrates, such as furniture assembly, cabinetry, and interior trim work. The strong, vibration‑resistant threads make them ideal for mounting hardware in automotive interior panels, rail vehicle components, and marine fixtures where constant motion could otherwise loosen conventional fasteners.

In the construction machinery sector, the inserts provide a secure anchor point for control panels, sensor housings, and electronic enclosures that must withstand harsh vibration and temperature fluctuations. Their ease of installation means that field technicians can retrofit existing structures without extensive re‑machining, preserving the integrity of the original material.

For hobbyists and makers, the kit offers a straightforward method to add durable threaded sockets to DIY projects, from custom shelving to electronic prototypes. The ability to install the inserts with a standard drill and tap tool makes them accessible to users with basic workshop equipment.

FAQ

What materials are compatible with these self‑tapping inserts?

The inserts are designed for use in wood, engineered wood products, composite panels, and certain plastics. They perform well in both soft and hardwoods, providing a strong, reusable thread without causing material damage.

Do I need special tools to install the inserts?

A standard drill with the appropriate drill bit size for the outer diameter, followed by a tap tool matching the inner M2*0.4 thread, is sufficient. No additional specialized equipment is required, making the installation process straightforward for most workshops.

How much load can each insert safely handle?

Each insert is engineered to withstand high tension loads typical of furniture assembly and equipment mounting. While exact load capacity depends on the substrate material and installation quality, the design ensures reliable performance well beyond standard consumer‑grade fasteners.

Are the inserts reusable after removal?

Yes, the inserts can be removed and reinstalled multiple times without significant loss of thread integrity, provided they are not damaged during extraction. This reusability makes them a cost‑effective solution for applications that may require future adjustments or repairs.

What warranty does Focket offer on these inserts?

Focket provides a limited one‑year warranty covering material defects and manufacturing errors. Should any issue arise within this period, contact our support team for a replacement or refund, subject to verification of the problem.
