Value Collection R57900579 Slotted Spring Pin 20mm 3mm Steel

Product Description

The VALUE COLLECTION R57900579 is a slotted spring pin manufactured from 1070-1080 grade carbon steel with a plain finish. Slotted spring pins, also called roll pins, are cylindrical fasteners with a longitudinal slot that allows the pin to compress on insertion and exert outward spring pressure against the hole wall. This design provides a secure, vibration-resistant fit without adhesives or secondary locking hardware. The R57900579 measures 20 mm in overall length and 3 mm in diameter. It is sized for metric fastening applications and is installed by maintenance technicians, millwrights, and mechanical assemblers working on machinery, equipment frames, and component assemblies.

This slotted spring pin is suited for general-purpose mechanical assembly and repair applications across manufacturing, industrial maintenance, and trade service environments. The metric dimensions make it appropriate for equipment designed to international or metric-standard specifications. A plain finish indicates no additional corrosion coating, making this pin best suited for dry or protected indoor environments. Minimum order quantity is 100 pieces; individual package quantity is 1.

Key Features

• Slotted design compresses on insertion for a spring-loaded, vibration-resistant fit
• 1070-1080 carbon steel construction provides strength and hardness appropriate for general fastening loads
• 20 mm overall length in metric sizing
• 3 mm nominal diameter fits standard metric bore holes
• Plain finish for use in dry or protected applications
• Minimum order quantity of 100 pieces ensures supply for production or high-volume repair use

Compatibility

Designed as a general-purpose metric slotted spring pin for use in mechanical assemblies requiring a 3 mm diameter roll pin in a 20 mm length.

Installation Notes

Slotted spring pins are installed by driving them into a drilled through-hole or blind hole using a pin punch and hammer or a pneumatic press. Power down and de-energize any equipment before servicing pinned assemblies. Ensure the receiving hole diameter is within the pin manufacturer's recommended tolerance range for proper retention. Removal is performed with a pin punch of appropriate diameter driven from the accessible end.
