Spring Pin 0.625 in x 1.5 in High Carbon Steel Unplated, Pkg Qty 10

Overview

These high-carbon steel spring pins are engineered for heavy-duty industrial applications requiring superior retention and vibration resistance. Designed with a robust slotted construction, each pin compresses slightly during installation to exert continuous radial pressure against the bore wall. This mechanism ensures a secure, self-locking fit that maintains integrity under dynamic loads and harsh operating conditions. The unplated finish provides a raw steel surface ideal for environments where additional coatings are unnecessary or where subsequent painting or plating of the assembly is planned. Sold in convenient packages of ten, these fasteners offer a reliable and cost-effective solution for aligning, locating, and securing mechanical components in machinery, automotive assemblies, and structural frameworks.

Key Features

High carbon steel construction delivers exceptional shear strength and durability Slotted design allows for controlled compression and consistent clamping force Unplated finish suitable for diverse industrial finishing requirements Precision manufactured to maintain tight tolerances for standard bores Excellent vibration resistance prevents loosening in dynamic applications Package quantity of ten supports efficient inventory management for maintenance teams

Applications

Heavy machinery assembly and maintenance Automotive powertrain and chassis component alignment Hydraulic cylinder pivot points and linkage systems Railroad equipment and rolling stock fabrication Agricultural implement manufacturing Construction equipment structural joints General industrial repair and retrofitting projects where precise hole reaming is not feasible These spring pins eliminate the need for expensive precision reaming often required by solid dowel pins, as the slot accommodates minor variations in hole diameter while maintaining high holding power. The 0.625-inch diameter and 1.5-inch length make them particularly well-suited for medium to large-scale mechanical connections where significant load-bearing capacity is essential. Their ability to absorb shock and resist fatigue makes them a preferred choice for equipment subjected to constant movement or impact. By providing a permanent yet removable fastening solution, they facilitate easier disassembly for service compared to riveted or welded connections, reducing downtime during routine inspections or part replacements.
