Value Collection R57900651 Slotted Spring Pin 20mm 4mm Steel

Product Description

The VALUE COLLECTION R57900651 is a slotted spring pin manufactured from 1070-1080 grade carbon steel with a plain finish. Slotted spring pins are cylindrical fasteners with a longitudinal slot that allows the pin to compress on insertion and exert radial pressure against the hole wall, creating a secure, vibration-resistant fit without adhesives or secondary fasteners. This pin measures 20 mm in overall length with a 4 mm diameter, making it a standard metric size suited for light-to-medium duty fastening applications. Installation requires no special tooling beyond a pin punch and hammer. Machinists, millwrights, and assembly technicians are the primary installers.

This slotted spring pin is intended for metric assembly applications where a removable, reusable pin fastener is required. Common use cases include aligning or retaining components in mechanical assemblies, fixtures, machine tools, and general industrial equipment. The metric dimensioning makes it appropriate for equipment designed to ISO or DIN standards. The plain steel finish is suitable for dry or lightly lubricated environments where corrosion resistance is not the primary concern.

Key Features

• 1070-1080 carbon steel construction provides reliable strength for general-duty fastening
• Slotted design allows radial compression for a friction-fit hold in the mating hole
• 20 mm overall length in a standard metric form factor
• 4 mm diameter fits common metric bores and drilled holes
• Plain finish suitable for controlled or lightly lubricated environments
• Sold individually; minimum order quantity of 100 units per order

Compatibility

Designed as a standard metric slotted spring pin for use in mechanical assemblies, fixtures, and industrial equipment requiring a 4 mm diameter, 20 mm long compression-fit pin fastener.

Installation Notes

Installation is typically performed by machinists or mechanical assemblers using a pin punch and hammer or a press. Ensure the receiving hole is drilled or reamed to the correct tolerance for a 4 mm slotted spring pin before driving. Do not exceed the shear load rating of the pin for the application. Inspect the pin and hole for burrs or damage before and after installation.
