Threaded Clinching Screw

A threaded clinching screw is a fastener that securely embeds a screw into a metal sheet through cold riveting. Unlike traditional welding or thread tapping, it creates a stable connection in thin sheets or soft metals without requiring additional processing. This structure creates a "mechanical interlock" between the screw and the base material, maintaining excellent anti-loosening properties and high torque carrying capacity, even in environments subject to vibration, high loads, or thermal cycling.

Products Description

The rapid development of new energy equipment, intelligent manufacturing, and the electronics industry has placed higher demands on the precision, strength, and assembly efficiency of metal fasteners. Threaded Clinching Screws, with their reliable locking performance, sophisticated structural design, and excellent assembly consistency, are widely used in metal enclosures, sheet metal parts, control boxes, energy battery modules, and industrial electronic equipment, becoming a key component for efficient assembly and structural stability.

Product Features

High-strength self-clinching structure

A special rolled tooth profile creates plastic deformation between the Self-Clinching Compression Screw and the base material during the press-fit process, achieving a permanent lock.

Unaffected by weld quality, there's no heat-affected zone, ensuring stable assembly strength.

Precise thread tolerance control

Each thread is CNC-turned and automatically inspected to ensure thread dimensions conform to ISO and DIN standards.

Excellent concentricity and pitch consistency reduce assembly slippage and snapping.

Excellent vibration and anti-loosening capabilities

A cold-pressed, embedded structure creates a metal interlock, combined with a surface anti-loosening coating (optional Loctite or nylon anti-loosening film), ensuring long-term stable operation in vibrating environments.

Environmentally friendly coating and corrosion resistance

A variety of corrosion-resistant finishes are available, including zinc plating, nickel plating, tin plating, Dacromet, and black oxide, meeting RoHS and REACH standards.

Multiple Customizations

We offer a variety of sizes and lengths, from M2 to M8, and can customize your design.

We support various head configurations, including flat, cup, and countersunk.
