Value Collection 601502BR Set Screw 7/8-14 Cup Point Alloy Steel

Product Description

The VALUE COLLECTION 601502BR is a cup point set screw designed for secure, semi-permanent fastening in mechanical assemblies. Manufactured from alloy steel to the ASTM F912 material grade, this fastener meets ASME/ANSI B18.3 dimensional standards. It features a 7/8-14 UNF thread with an overall length of 2.5 inches and is driven by a 1/2-inch hex key. The cup point bites into the mating surface under torque, providing strong resistance to rotation and axial movement. Machinists, millwrights, and maintenance technicians install this type of fastener when locking shafts, collars, gears, and similar components in position without exposed fastener heads.

This set screw is suited for industrial and commercial mechanical applications where a flush or recessed fastener is required. Typical installations include shaft-to-collar connections, set collar locking, gear hub retention, and similar assemblies found in manufacturing equipment, conveyor systems, and mechanical power transmission setups. The unified fine thread pitch provides tighter thread engagement and higher clamping force per turn compared to coarse thread variants, making it appropriate for applications subject to vibration or dynamic loading.

Key Features

• Cup point geometry bites into the mating surface for strong rotational and axial holding force
• 7/8-14 UNF thread for fine-pitch engagement and vibration resistance
• Alloy steel construction rated to ASTM F912 material grade
• Conforms to ASME/ANSI B18.3 dimensional standard for hex socket set screws
• 1/2-inch hex key drive for installation with standard hex wrenches or L-keys
• Overall length of 2.5 inches suitable for deeper shaft or hub penetration requirements

Compatibility

Designed as a standard hex socket cup point set screw per ASME/ANSI B18.3, compatible with any 7/8-14 UNF tapped hole in mechanical assemblies requiring flush fastening.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 1/2-inch hex key or allen wrench. De-energize and lock out all associated machinery before installing or removing set screws per applicable OSHA lockout/tagout procedures. Ensure the mating tapped hole is clean and free of debris before threading the fastener. Do not exceed the design torque capacity of the tapped material, particularly in softer substrates such as aluminum or brass.
