Value Collection 141025PR Set Screw 8-32 X 3/8 in Half Dog Point

Product Description

The VALUE COLLECTION 141025PR is a half dog point set screw designed for secure, flush-mount fastening in mechanical assemblies. It features an 8-32 UNC thread and measures 3/8 inches in overall length. The screw is machined from Grade 8 alloy steel, providing high tensile strength suited for demanding industrial and mechanical applications. Drive engagement is through a 5/64-inch hex socket. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards, making it appropriate for precision assemblies where dimensional and material compliance is required. Installation is performed with a standard hex key or Allen wrench of the matching drive size.

This set screw is commonly used to secure collars, pulleys, gears, and similar components onto shafts in both light industrial and general mechanical applications. The half dog point seats into a mating hole or flat on a shaft to prevent rotation and axial movement without the need for a through-fastener. It is well suited for machinery maintenance, fabrication shops, and equipment assembly where repeatable positioning and reliable clamping force are needed.

Key Features

• Half dog point design for positive shaft location and anti-rotation seating
• 8-32 UNC thread standard for compatibility with common tapped holes
• Grade 8 alloy steel construction for high tensile and torsional strength
• 5/64-inch hex drive for precise torque application with a standard hex key
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Fractional inch measurement type for straightforward sizing and sourcing

Compatibility

Designed as an OEM-style replacement or standard-stock set screw for mechanical assemblies requiring an 8-32 UNC half dog point fastener in alloy steel.

Installation Notes

Installation is typically performed by a machinist, maintenance technician, or mechanical assembler using a 5/64-inch hex key. Always de-energize or lock out any powered equipment before servicing fasteners in rotating assemblies. Ensure the mating tapped hole is clean and free of debris before driving the screw. Do not exceed the torque capacity of the alloy steel fastener, and verify the dog point seats fully into the shaft detent or flat before returning equipment to service.
