Value Collection 121010PR Set Screw 5-40 X 3/16 in Cone Point

Product Description

The VALUE COLLECTION 121010PR is a cone point set screw designed for secure, permanent-position fastening in mechanical assemblies. Manufactured from Grade 8 alloy steel, it provides high tensile strength and resistance to loosening under load. The cone point digs into the mating surface to lock the fastener in place, making it well suited for applications where the screw must resist rotation or axial movement. It uses a 1/16-inch hex drive and conforms to ASME/ANSI B18.3 and ASTM F912 standards. Machinists, tool-and-die technicians, and mechanical assemblers are the typical installers of this fastener.

This set screw is used in light-duty mechanical assemblies where a #5-40 UNC thread is specified. Common applications include locking collars, pulleys, gears, and knobs onto shafts in small machinery, instrumentation, and precision equipment. The cone point style is preferred when a permanent or semi-permanent hold is required and surface marring of the shaft is acceptable. This item is sold individually but is subject to a minimum order quantity of 100 pieces per order.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength
• Cone point tip bites into mating surface for strong, positive retention
• 1/16-inch hex (Allen) drive for precise installation with standard hex keys
• #5-40 UNC thread size for use in fine-pitch light fastening applications
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Fractional inch measurement — 3/16-inch overall length

Compatibility

Designed as a standard #5-40 UNC cone point set screw suitable for use in any mechanical assembly requiring an ASME/ANSI B18.3-compliant socket set screw in this thread size and length.

Installation Notes

Installation is performed by mechanical technicians or machinists using a 1/16-inch hex key. Ensure the mating shaft and threaded hole are clean and free of debris before driving the screw. Apply the hex key fully into the drive socket to avoid rounding the drive. Torque to the assembly specification provided by the equipment manufacturer — no torque value is specified for this fastener in the product data.
