Value Collection R57700101 Slotted Spring Pin 3/8 in

Product Description

The VALUE COLLECTION R57700101 is a slotted spring pin designed for use in mechanical assemblies requiring a reliable, friction-fit fastening solution. Manufactured from 1070-1090 alloy steel with a plain finish, this pin measures 3/8 inch in overall length and 3/32 inch in diameter. The slotted design allows the pin to compress on insertion and expand against the bore wall, creating a secure, vibration-resistant fit without secondary fasteners. It is commonly installed by machinists, maintenance technicians, and assembly workers in light to medium-duty mechanical applications.

This slotted spring pin is suited for use in shafts, linkages, hinges, and similar assemblies where a removable or semi-permanent pin connection is required. The plain finish is appropriate for indoor or protected environments. The 1070-1090 alloy steel construction provides adequate hardness and spring-back characteristics for standard inch-system applications across industrial and commercial equipment maintenance scenarios.

Key Features

• Slotted design compresses for insertion and expands to grip bore walls without adhesive or threading
• Overall length of 3/8 inch for compact fastening applications
• Diameter of 3/32 inch for precise bore fitment in inch-system assemblies
• 1070-1090 alloy steel construction provides consistent spring properties and hardness
• Plain finish suitable for protected indoor environments

Compatibility

Designed as a standard-inch-system slotted spring pin for use in mechanical assemblies requiring a 3/32 inch diameter bore and 3/8 inch pin length.

Installation Notes

Installation is typically performed using a pin punch and hammer or an arbor press to drive the pin into the prepared bore. Ensure the bore diameter matches the pin nominal diameter for proper spring engagement. Wear appropriate eye protection during installation and removal. Removal requires a punch slightly smaller than the pin diameter to drive the pin clear of the bore without damaging surrounding material.
