Value Collection R57900839 Slotted Spring Pin 40mm 10mm Steel

Product Description

The VALUE COLLECTION R57900839 is a slotted spring pin manufactured from 1070-1080 grade carbon steel with a plain finish. Slotted spring pins are cylindrical fasteners with a lengthwise slot that allows the pin to compress on insertion and exert radial pressure against the bore wall, creating a secure, vibration-resistant fit without adhesives or threading. This pin measures 40 mm in overall length and 10 mm in diameter, making it suited for medium-duty fastening applications in mechanical assemblies. It is installed by machinists, maintenance technicians, and mechanical assemblers working with metric hardware in industrial and manufacturing environments.

This slotted spring pin is used in applications where two components must be aligned or retained with a removable but secure connection. Common installations include shaft-to-hub assemblies, linkage components, and machine frames where metric fastening is required. The pin follows a metric system of measurement and carries the UNSPSC commodity code 31163201. It does not meet military specifications and is intended for commercial and industrial use. This SKU is sold individually, with a minimum order quantity of 25 units.

Key Features

• 40 mm overall length in metric sizing for precision fitment in metric-dimensioned bores
• 10 mm diameter with slotted design for compression fit and radial retention force
• 1070-1080 grade carbon steel construction provides strength and durability under shear loads
• Plain finish suitable for general industrial environments
• Does not require threading, adhesives, or special tools for basic installation
• Sold per piece with a minimum order quantity of 25 units

Compatibility

Designed as an OEM-style replacement or standard-stock slotted spring pin for metric mechanical assemblies requiring a 10 mm diameter by 40 mm long compression-fit pin in carbon steel.

Installation Notes

Slotted spring pins are typically installed by mechanical technicians using a pin driver or arbor press to seat the pin flush or to the required depth within the bore. Ensure the receiving bore is clean and within specified diameter tolerance before installation. Always de-energize and lock out any machinery before servicing assemblies that contain spring pins. Removal is performed with a punch and hammer or pin extractor tool; avoid reusing pins that show deformation or cracking along the slot.
