Value Collection 101173PR Set Screw 6-40 X 5/16 in Cup Point

Product Description

The VALUE COLLECTION 101173PR is a cup point set screw designed for secure fastening in mechanical assemblies where a flush or recessed installation is required. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength suitable for demanding industrial and trade applications. It features a 6-40 UNF thread with an overall length of 5/16 inches and is driven by a 1/16 inch hex key. The cup point geometry bites into the mating surface to resist rotational and axial movement. Meets ASME/ANSI B18.3 and ASTM F912 standards. Machinists, maintenance technicians, and mechanical contractors are the typical installers of this fastener type.

This set screw is suited for use in light-duty mechanical assemblies such as collars, pulleys, gears, knobs, and shaft-mounted components where a set screw is required to lock a part to a shaft or surface. The 6-40 UNF thread designation makes it appropriate for precision instrument work, small-diameter shaft applications, and assemblies requiring fine-thread engagement. It is sold individually with a minimum order quantity of 100 pieces per order.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength
• Cup point geometry grips mating surface to prevent rotation and axial shift
• 6-40 UNF fine thread for precise engagement in small-diameter applications
• 1/16 inch hex drive compatible with standard hex keys and Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and performance standards
• Fractional inch sizing for straightforward measurement and replacement

Compatibility

Designed as an OEM-style replacement or stock fastener for mechanical assemblies requiring a 6-40 UNF cup point set screw with a 1/16 inch hex drive and 5/16 inch overall length.

Installation Notes

Set screws of this type are installed by machinists and mechanical maintenance technicians using a 1/16 inch hex key or Allen wrench. De-energize and lock out any equipment before installing or replacing set screws in rotating assemblies. Do not overtighten, as small-diameter alloy set screws can be damaged if torque is applied beyond their rated capacity. Verify thread engagement depth and mating surface condition before final tightening.
