Value Collection R57700631 Slotted Spring Pin 2in 5/16in

Product Description

The VALUE COLLECTION R57700631 is a slotted spring pin manufactured from 18-8 stainless steel. Slotted spring pins, also known as roll pins, are cylindrical fasteners with a lengthwise slot that allows the pin to compress during insertion and exert radial force against the bore wall once seated. This design provides a secure, vibration-resistant fit without requiring precise hole tolerances. At 2 inches in overall length and 5/16 inch in diameter, this pin suits medium-duty fastening and alignment applications across industrial, mechanical, and trade settings. Machinists, maintenance technicians, and assembly personnel are the primary installers.

This slotted spring pin is used in mechanical assemblies where a driven, removable, or semi-permanent pin connection is needed. Typical applications include shaft-to-hub connections, hinge pivots, linkage assemblies, and component alignment in equipment subject to vibration or lateral loading. The 18-8 stainless steel construction makes it suitable for environments with exposure to moisture, mild chemicals, or corrosive conditions where carbon steel would degrade. It is sized for use in standard 5/16 inch bored holes.

Key Features

• Slotted design compresses on insertion for a secure, self-retaining fit in standard bored holes
• 18-8 stainless steel provides corrosion resistance in wet or mildly corrosive environments
• 2 inches overall length suits medium-depth bore and through-hole applications
• 5/16 inch diameter compatible with standard nominal hole sizing
• Inch measurement system — integrates directly with standard imperial tooling and drawings

Compatibility

Designed as an OEM-style replacement or direct-use slotted spring pin for mechanical assemblies requiring a 5/16 inch diameter, 2 inch long roll pin in 18-8 stainless steel.

Installation Notes

Slotted spring pins are typically driven into place using a pin punch and hammer or an arbor press — do not use an impact tool in a way that deforms the slot beyond its designed compression range. Ensure the receiving bore is clean and free of burrs before installation. Pins can be removed with a punch driven from the blind end of the hole; avoid reusing a pin that has been deformed or cracked during removal. No special electrical lockout is required, but always de-energize or de-pressurize any assembly before servicing fasteners under load.
