Cold Forged Shaft Pin for Precision Machinery and Fixture Applications

This Cold Forged Shaft Pin for Precision Machinery And Fixture Applications from Qimao Metal Manufacturer is made through cold forging, not machining from bar stock. The process uses high-grade carbon steel or alloy steel like 20Cr or 1045. Cold forging aligns the grain flow along the pin's shape, so it gets better impact resistance than cut pins. Diameters range from 3mm to 25mm, lengths from 10mm to 120mm. Surface finish hits Ra 1.6 without extra grinding. Tolerances hold to g6 or h6 classes. No undercuts or step marks at the chamfer transitions. Each batch gets a hardness test and a random sample sectioning to check for internal voids. Packed in oiled paper inside rigid cartons.

Ideal for jigs, fixtures, indexing tables, and linear motion guides, this pin provides reliable alignment, load transfer, and rotational stability. Cold forging eliminates cutting waste while improving surface hardness and fatigue resistance compared to machined alternatives.

Reduces production costs, increases shear strength, and extends service life in repetitive high-cycle operations.

Product Parameter (Specification)

Product Feature

1-The cold forged structure means no material waste and no interrupted grain lines. That gives higher shear strength compared to turned pins.

2-The Qimao Metal Manufacturer’s Cold Forged Shaft Pin surface is smooth and slightly work-hardened during forming, raising wear resistance on the outer layer.

3-The ends have consistent chamfers, so they start straight when pressed into fixture plates.

4-Fourth, the price stays stable for medium and large batches because the process takes less time per part than screw machining.

5-Diameters vary little from pin to pin, within 0.01mm on most lengths. These features make troubleshooting easier on automated assembly lines.

Our Factory Advantage

1. We run cold heading machines from Taiwan, each with real-time diameter monitoring. Our tool shop makes the carbide dies in-house, so we control the Cold Forged Shaft Pin for Precision Machinery And Fixture Applications quality and the lead time.

2. For sizes above 10, 000 pieces, we hold the price 15–20% lower than machined pins.

3. Every shift does a first-article inspection on a digital comparator.

4. We stock the three most common diameters—6mm, 8mm, 10mm—for same-day shipment.

5. Engineers stay on the floor, not in a separate office. We focus all detail as your requirements.

How To use The Products:

Start by checking the hole diameter in your fixture plate or machinery housing. The Cold Forged Shaft Pin for Precision Machinery And Fixture Applications should push in with thumb pressure for the last two millimeters. If it goes in too easily, the hole is oversized. Use a depth stop on an arbor press for consistent insertion depth across multiple pins. For locating duties, press the pin until the shoulder contacts the plate surface. For hinge or pivot applications, leave 0.05mm to 0.10mm axial clearance. Never hammer a cold forged pin directly unless the head is flat and supported. To remove a stuck pin, drill a small extraction hole from the blind side. Lubricate only with light oil, never grease, to avoid hydraulic lock.
