Clamping PinThis 8mm by 4mm clamping pin is a short, heavy roll pin used to retain components on forklift assemblies where shear capacity matters more than engagement length. Service techs replace clamping pins after disassembly because driving them out distorts the spring profile. The correct pin diameter and length are critical, since oversized pins damage the receiving bore and undersized pins fail to retain the joint. Sold as an aftermarket replacement, contact us to verify outer diameter, length, and wall thickness class before ordering, since clamping pins of similar nominal size vary in spring rate, and substituting between standards changes shear capacity under operating retention load significantly.Aftermarket replacement part, cross-references original part number AC04025-00408.Need help confirming fit?
