Value Collection 151226PR Set Screw 1/4-20 X 3/8 in Flat Point

Product Description

The VALUE COLLECTION 151226PR is a 1/4-20 UNC flat point set screw manufactured from Grade 8 alloy steel. Set screws are headless fasteners used to secure a component — such as a collar, gear, pulley, or hub — against or onto a shaft by bearing force through a point contact. The flat point style distributes clamping load across a small surface area, making it well suited for applications where the mating surface must remain undamaged. This screw is driven with a 1/8-inch hex key and meets ASME/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and maintenance technicians are the primary installers.

This set screw is appropriate for general industrial, mechanical, and maintenance applications requiring a secure, low-profile fastener in a 1/4-20 threaded bore. The 3/8-inch overall length and flat point geometry are commonly specified in light-duty shaft locking, fixture assembly, and equipment positioning tasks. Grade 8 alloy steel construction provides higher tensile strength than standard steel fasteners, making it suitable for moderate-load mechanical assemblies in manufacturing, HVAC equipment, and similar trade environments.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard threaded bores
• Flat point design minimizes surface damage to mating shafts or components
• Grade 8 alloy steel construction for elevated tensile strength
• 1/8-inch internal hex drive for precise torque application with a standard hex key
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Headless profile sits flush or below surface for clearance-sensitive installations

Compatibility

Designed as a standard 1/4-20 UNC flat point set screw for use in any threaded bore conforming to that thread specification where a flat point and 3/8-inch length are required.

Installation Notes

Installation is performed with a 1/8-inch hex key; ensure the key is fully seated in the drive recess before applying torque to prevent rounding. De-energize and lock out any equipment before accessing shaft assemblies or rotating components. Verify thread engagement depth and confirm the mating bore is clean and free of debris prior to installation. Follow applicable facility maintenance standards and equipment manufacturer guidelines for fastener seating procedures.
