Value Collection R57900887 Slotted Spring Pin 70mm 12mm Steel

Product Description

The VALUE COLLECTION R57900887 is a slotted spring pin manufactured from 1070-1080 grade steel with a plain finish. Slotted spring pins compress radially when driven into a hole, creating a secure press fit that resists vibration and axial movement. This pin measures 70 mm in overall length and 12 mm in diameter, placing it in the medium-to-large fastener range suitable for heavy-duty mechanical assemblies. The plain finish offers basic surface protection adequate for indoor and low-moisture environments. Machinists, millwrights, and mechanical assemblers commonly install these pins in production and maintenance applications across industrial equipment and machinery.

Slotted spring pins are widely used in mechanical assemblies requiring a removable or semi-permanent retained connection between shafts, hubs, levers, and linkages. This metric-dimensioned pin suits applications where components are designed to metric tolerances, including imported machinery, industrial conveyors, agricultural equipment, and general manufacturing fixtures. The 1070-1080 steel grade provides a balance of hardness and flexibility appropriate for dynamic load conditions. This item is sold individually but must be ordered in multiples of 25.

Key Features

• Slotted design allows radial compression for secure press-fit installation and removal
• 1070-1080 steel construction provides hardness and flexibility under dynamic loads
• 70 mm overall length and 12 mm diameter for medium-to-large mechanical assemblies
• Plain finish suitable for dry and low-moisture indoor environments
• Metric dimensioning for compatibility with metric-tolerance equipment and machinery
• Minimum order quantity of 25 units makes this suitable for production and maintenance stocking

Compatibility

Designed as a standard metric slotted spring pin for general mechanical assemblies using 12 mm bore holes and requiring a 70 mm pin length.

Installation Notes

Slotted spring pins are typically installed by machinists or millwrights using a pin punch and hammer or an arbor press. De-energize and lock out all equipment before installing or removing pins from rotating or moving assemblies. Ensure the receiving hole diameter matches the pin specification to achieve proper interference fit. Reuse of spring pins after removal is not recommended, as repeated compression cycles can reduce retention force.
