Value Collection 601076PR Set Screw 3-56 X 3/8 in Cup Point

Product Description

The VALUE COLLECTION 601076PR is a cup point set screw designed for secure, reliable fastening in precision mechanical assemblies. It features a 3-56 UNF thread and an overall length of 3/8 inches. The cup point geometry bites into mating surfaces to resist rotation and axial movement without requiring a through-hole. Manufactured from alloy steel to ASTM F912 and ASME/ANSI B18.3 standards, this screw delivers consistent hardness and shear strength suited to demanding production and maintenance applications. Installation uses a 0.05-inch hex key drive.

This set screw is used in small-diameter shaft-to-hub connections, set collar assemblies, and mechanical linkage components where a compact fastener profile is required. The 3-56 UNF thread is common in instrumentation, light machinery, and precision motion hardware. It is installed by machinists, maintenance technicians, and mechanical assemblers working on OEM equipment, production fixtures, and field-service repairs that require a low-profile locking fastener.

Key Features

• Cup point geometry grips mating surfaces to prevent rotation and axial shift
• 3-56 UNF thread for use in small-diameter precision assemblies
• Alloy steel construction meets ASTM F912 material and hardness requirements
• Conforms to ASME/ANSI B18.3 dimensional standard for inch hex socket set screws
• 0.05-inch hex key drive for installation in confined or recessed locations
• Overall length of 3/8 inches suits shallow boss and collar applications

Compatibility

Designed as a standard ASME/ANSI B18.3 inch-series hex socket set screw suitable for any threaded 3-56 UNF socket in mechanical assemblies requiring a cup point fastener.

Installation Notes

A calibrated 0.05-inch hex key or T-handle driver is required for proper installation. De-energize and lock out any rotating or powered equipment before servicing set screws in shaft assemblies. Do not overtighten; excessive torque can strip the small thread or damage the mating shaft. Consult applicable machinery manufacturer torque guidelines and relevant ASME standards when installing in safety-critical applications.
