Value Collection R57700303 Slotted Spring Pin 2-3/4 in

Product Description

The VALUE COLLECTION R57700303 is a slotted spring pin used to secure components in assemblies where controlled, radial force retention is required. At 2-3/4 inches long and 7/16 inches in diameter, this pin is manufactured from 1070-1090 alloy steel with a plain finish. The slotted design allows the pin to compress during insertion and exert consistent outward pressure against the hole wall, creating a firm, vibration-resistant fit without the need for threads or fasteners. Machinists, millwrights, and maintenance technicians install these pins in shafts, linkages, hinges, and general mechanical assemblies across industrial and commercial equipment.

This slotted spring pin is suited for use in mechanical assemblies requiring removable, press-fit retention in inch-dimensioned bores. Typical applications include shaft-to-hub connections, locking levers, actuator linkages, and pivot assemblies. The plain finish makes it appropriate for dry or lightly lubricated indoor service environments. This pin is sold individually per package.

Key Features

• Slotted design compresses on insertion for a secure radial fit without threading
• 1070-1090 alloy steel construction provides strength and spring-back retention force
• Plain finish suitable for general-purpose mechanical assemblies
• Inch-dimensioned: 2-3/4 inches long, 7/16 inches diameter
• Does not meet military specifications — intended for standard commercial applications

Compatibility

Designed for use in inch-dimensioned bores requiring a 7/16-inch slotted spring pin. Suitable as a general-purpose replacement or new-install pin in mechanical assemblies across industrial, commercial, and maintenance applications where this pin geometry is specified.

Installation Notes

Slotted spring pins are installed by machinists or maintenance technicians using a pin punch and hammer or an arbor press. The receiving bore diameter should match the pin nominal diameter per standard engineering tolerances to ensure proper retention force. Always inspect the bore for burrs or damage before installation. Do not install in applications requiring pins that meet military specifications.
