Value Collection 151208PR Set Screw 1/4-20 X 3/16 in Flat Point

Product Description

The VALUE COLLECTION 151208PR is a 1/4-20 flat point set screw designed for secure, non-marring clamping and positioning applications in mechanical assemblies. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and resistance to shear forces in demanding industrial and trade environments. The 3/16-inch overall length and 1/8-inch hex drive make it suitable for tight-clearance installations. It conforms to ASME/ANSI B18.3 and ASTM F912 standards, confirming dimensional accuracy and material compliance. Licensed tradespeople and maintenance technicians working on shaft collars, hubs, pulleys, and similar components will find this screw a reliable, standards-compliant choice.

This set screw is used in applications where a rotating or sliding component must be locked to a shaft without protruding hardware. Common install scenarios include motor shaft collars, set-collar assemblies, gear hubs, and fixture mounts in residential and commercial mechanical systems. The flat point distributes clamping load across the shaft surface, minimizing surface damage. The 1/4-20 UNC thread is one of the most widely used coarse-thread standards in North American trade work, making this fastener broadly applicable across HVAC, plumbing, and general mechanical service.

Key Features

• Grade 8 alloy steel construction for high tensile and shear strength
• Flat point design distributes load and reduces shaft marking
• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes
• 1/8-inch hex drive for use with standard hex keys or Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Compact 3/16-inch overall length suits confined-space and shallow-bore applications

Compatibility

Designed as a standard 1/4-20 UNC flat point set screw for use in any tapped hole or collar assembly requiring a 1/4-20 coarse thread fastener with a 1/8-inch hex drive.

Installation Notes

Installation is performed with a 1/8-inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive. De-energize and lock out any associated mechanical or electrical equipment before servicing shaft assemblies. Verify thread engagement depth is sufficient for the load requirements of the application. Follow applicable ASME or facility maintenance standards for fastener torque and inspection intervals.
