Value Collection 151001PR Set Screw 4-40 X 1/8 in Flat Point

Product Description

The VALUE COLLECTION 151001PR is a Grade 8 alloy steel set screw with a flat point tip and hex drive, designed for securing components on shafts or within assemblies where a flush or non-protruding point is required. Sized at 4-40 UNC thread with an overall length of 1/8 inch, this fastener meets ASME/ANSI B18.3 and ASTM F912 standards. The hex drive requires a 0.050-inch hex key for installation. Grade 8 alloy steel construction provides the hardness and shear resistance needed in demanding mechanical assemblies where standard steel fasteners may not hold.

This set screw is suited for light mechanical assemblies, precision instruments, electrical hardware, and small-bore shaft collars where a 4-40 UNC thread pattern is specified. The flat point style distributes clamping force across the bearing surface without marring the shaft, making it appropriate for softer shaft materials or applications requiring repeatable positioning. Sold in minimum order quantities of 100 per order, with individual package quantity of 1.

Key Features

• Grade 8 alloy steel construction for high hardness and tensile strength
• Flat point tip distributes load without damaging shaft surfaces
• Hex drive requires a 0.050-inch hex key for installation
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• 4-40 UNC thread form for compatibility with standard 4-40 tapped assemblies

Compatibility

Designed as a standard 4-40 UNC set screw for use in any assembly requiring a flat point, hex drive fastener conforming to ASME/ANSI B18.3 specifications.

Installation Notes

Installation is performed using a 0.050-inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. De-energize or lock out any machinery before accessing shaft assemblies or rotating components. Thread engagement and seating should be verified after installation, particularly in vibration-prone environments where a thread-locking compound may be appropriate per assembly requirements.
