Value Collection 40407 Set Screw 7/16-14 X 1 in Cup Point Grade 8

Product Description

The VALUE COLLECTION 40407 is a cup point set screw designed for mechanical assemblies requiring a strong, non-projecting fastener. Threaded 7/16-14 UNC with an overall length of 1 inch, this screw is manufactured from alloy steel to Grade 8 specifications, delivering high tensile and torsional strength in demanding industrial and maintenance applications. The cup point geometry bites into the mating shaft surface to resist rotation and axial movement. Drive is a 7/32-inch hex key socket, conforming to ASME/ANSI B18.3 and ASTM F912 standards. Installation requires a standard 7/32-inch Allen wrench.

Cup point set screws like the 40407 are commonly used in shaft collars, pulleys, sprockets, gears, and couplings where a flush or recessed fastener is required. The cup point creates a small indentation in the shaft for positive retention without damaging the shaft beyond the seating area. This screw suits general industrial machinery, HVAC drive assemblies, pump shafts, and fabrication applications where UNC 7/16-14 threading is specified. Installation is typically performed by millwrights, maintenance technicians, or mechanical assemblers.

Key Features

• Grade 8 alloy steel construction for high-strength, high-torque applications
• Cup point geometry provides positive shaft retention with controlled surface contact
• 7/16-14 UNC thread for broad compatibility with standard tapped holes
• 7/32-inch hex key drive per ASME/ANSI B18.3
• Meets ASTM F912 fastener standard
• 1-inch overall length suits medium-depth engagement requirements

Compatibility

Designed as a standard UNC replacement set screw for shaft collars, pulleys, couplings, and similar mechanical components tapped to 7/16-14 thread.

Installation Notes

De-energize and lock out all rotating equipment before removing or installing set screws. Use a properly sized 7/32-inch hex key to avoid rounding the drive socket. Do not exceed the rated torsional capacity of the screw by using extended-handle drivers or impact tools unless the application specifies it. Verify thread engagement depth meets the requirements of the assembly before final torque.
