Value Collection R57900741 Slotted Spring Pin 30mm 6mm Steel

Product Description

The VALUE COLLECTION R57900741 is a slotted spring pin manufactured from 1070-1080 grade carbon steel with a plain finish. Slotted spring pins are hollow, longitudinally slotted fasteners that compress radially upon insertion, creating a spring-loaded interference fit within a drilled hole. At 30 mm in overall length and 6 mm in diameter, this metric pin is sized for moderate-load applications where controlled flexibility and vibration resistance are required. The plain finish provides no additional corrosion protection, making it suited for dry or protected environments. This part does not meet military specifications. Installation is performed by maintenance technicians, millwrights, and mechanical assemblers working on precision mechanical assemblies.

This slotted spring pin is used in a wide range of mechanical assembly applications including shaft-to-hub connections, linkage assemblies, hinge pivots, and alignment fixtures. The metric dimensions make it appropriate for equipment designed to metric standards. Its steel construction and spring action allow it to absorb shock and vibration loads without loosening, which is a common requirement in industrial machinery, conveyor systems, and drive assemblies. The plain finish is acceptable in applications where the assembly is housed or otherwise protected from direct moisture exposure.

Key Features

• Slotted design allows radial compression for a secure interference fit in drilled holes
• 1070-1080 grade carbon steel construction for reliable strength in mechanical assemblies
• 30 mm overall length suits moderate-depth hole applications
• 6 mm diameter for metric-standard bore sizes
• Plain finish keeps installation straightforward in protected environments
• Spring action absorbs shock and vibration without fastener loosening

Compatibility

Designed as an OEM-style replacement or stock component for metric mechanical assemblies requiring a 6 mm slotted spring pin with 30 mm overall length.

Installation Notes

Slotted spring pins are typically installed using a pin punch and hammer or an arbor press; ensure the receiving hole is drilled to the correct diameter to achieve the proper interference fit. De-energize or lock out all equipment before servicing any assembly containing these pins. Avoid reusing spring pins that show signs of deformation, cracking, or reduced springback, as compromised pins may not retain the required holding force. Refer to applicable machinery maintenance standards for hole tolerance and pin replacement intervals.
