Value Collection 121112PR Set Screw 1/4-20 X 1/2 in Cone Point

Product Description

The VALUE COLLECTION 121112PR is a 1/4-20 UNC cone point set screw designed for secure, positive locking in mechanical assemblies. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and hardness suited to demanding industrial and trade applications. The cone point bites into the mating surface for a strong, slip-resistant hold. At 1/2 inch overall length and driven with a 1/8 inch hex key, it conforms to ASME/ANSI B18.3 and ASTM F912 standards. Machinists, maintenance technicians, and millwrights install this type of fastener in pulleys, collars, gears, and shaft assemblies.

This set screw is appropriate for use in light manufacturing, HVAC equipment assemblies, motor shaft collars, and general mechanical maintenance where a headless fastener is required. The cone point configuration is best suited for permanent or semi-permanent installations where the point is intended to indent or seat into the mating component. Sold individually per package with a minimum order quantity of 100 pieces, this SKU is suited for shop stock or production replenishment.

Key Features

• Grade 8 alloy steel construction for high tensile and hardness ratings
• Cone point design provides positive seating and strong axial holding force
• 1/4-20 UNC thread for broad compatibility with standard tapped holes
• 1/8 inch hex drive matches standard hex keys and Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Headless profile eliminates protrusion hazards in rotating assemblies

Compatibility

Designed as a standard 1/4-20 UNC cone point set screw suitable for any application requiring a headless fastener in a 1/4-20 tapped hole where cone point engagement is specified.

Installation Notes

Installation is performed with a 1/8 inch hex key torqued by hand to the assembly specification. Ensure the mating shaft or surface is clean and free of debris before seating the cone point, as contamination can cause improper seating. De-energize and lock out any machinery before servicing shaft collars, pulleys, or gear assemblies. Avoid overtightening, which can damage the cone point or the mating surface and compromise the hold.
