Value Collection 101034PR Set Screw 1-72 X 1/4 in Cup Point

Product Description

The VALUE COLLECTION 101034PR is a cup point set screw designed for secure, tamper-resistant fastening in precision mechanical assemblies. It features a 1-72 Unified Fine Thread (UNF) and an overall length of 0.25 inches. The cup point geometry bites into the mating surface to resist rotation and axial movement without a protruding head. Made from Grade 8 alloy steel, this screw delivers high tensile strength in a compact form factor. It is driven by a 0.0280-inch hex key. Manufactured to ASME/ANSI B18.3 and ASTM F912 standards, it meets the dimensional and mechanical requirements expected in industrial and precision applications.

This set screw is used in applications where a flush or recessed fastener is required, such as securing collars, pulleys, gears, and knobs to shafts. The fine 1-72 thread pitch is suited for thin-walled components or assemblies where precise clamping load control matters. Typical install environments include machine tools, instrumentation, and small mechanical devices. Machinists, maintenance technicians, and mechanical assemblers are the primary installers. The minimum order quantity is 10 pieces.

Key Features

• Cup point geometry bites into shaft surface to resist rotation and axial movement
• Grade 8 alloy steel construction provides high tensile and proof load strength
• 1-72 UNF thread for fine-pitch clamping in precision or thin-walled components
• Hex socket drive accepts a 0.0280-inch hex key for flush installation
• Manufactured to ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards
• Headless design sits fully recessed for zero protrusion in assembled hardware

Compatibility

Designed as a standard-dimension replacement or new-install set screw for any application requiring a 1-72 UNF, 1/4-inch overall length, cup point, Grade 8 alloy steel headless fastener per ASME/ANSI B18.3 and ASTM F912.

Installation Notes

Installation should be performed by a qualified machinist or mechanical technician using a calibrated 0.0280-inch hex key. De-energize and lock out any rotating equipment before installing or removing set screws. Do not exceed the torque capacity of the 1-72 thread by applying oversized tools or excessive force. Confirm the mating shaft or bore material is compatible with a cup point to avoid unintended surface damage where a flat or smooth shaft finish must be preserved.
