Precision Cold Formed Eccentric Locking Pins for Industrial
Fastening
As a leading manufacturer of high-tolerance fastening components,
we specialize in cold-formed eccentric locking pins engineered for
superior mechanical strength and vibration resistance. Available in
carbon steel and corrosion-resistant stainless steel, our pins
undergo strict quality control to ensure precise eccentricity and
dimensional accuracy. Customize every detail – from material grade
to surface treatments – based on your technical drawings or
samples. Ideal for automotive, machinery, and heavy-equipment
applications requiring reliable eccentric locking solutions.
Key Advantages:
✅ High Precision Cold Forming – Enhanced grain flow for 30% higher fatigue strength vs. machined
pins.
✅ Material Flexibility – Carbon steel (cost-effective) or stainless steel (A2/A4 corrosion
resistance).
✅ Full Customization – Tailored dimensions, tolerances, and surface treatments per your
specs.
✅ Rapid Prototyping – Sample delivery within 15 working days upon drawing approval.
✅ Certified Quality – ISO 9001:2015 compliant manufacturing with material traceability.

Cold Heading Advantage
1, production process without waste, save material cost, especially
precious metals and small head rod products.
2, through extrusion molding, maximum retention of material metal
streamline, not easy to break.
3, through cold work hardening, the material metal composition
arrangement dense, to achieve the advantages of good tensile
strength, high hardness, high torsion.
Fully automated production saves a lot of labor costs.
5, can produce M1.0-M20 products, the head can achieve 40.0mm, the
longest can achieve 300mm.
6, Taiwan imported equipment, high precision, multi-power equipment
can produce complex shape of hardware.
7, the material is more environmentally friendly, such as 304
stainless steel is food grade material, has good environmental
protection and corrosion resistance.
8, surface treatment, high finish, good adhesion, more easy to
coating.
All of the above products are produced by our company. Most of them
have complete sets of molds or some molds. If you find us, you can
