Value Collection 141100PR Set Screw 1/4-20 X 5/8 in Half Dog Point

Product Description

The VALUE COLLECTION 141100PR is a half dog point set screw designed for mechanical fastening applications where a protruding point is needed to locate or partially lock a mating part. Threaded 1/4-20 UNC with an overall length of 5/8 inches, this screw is manufactured from Grade 8 alloy steel, providing high tensile strength and resistance to shear forces. Drive is a 1/8-inch hex socket, requiring a hex key or Allen driver for installation. Conforms to ASME/ANSI B18.3 and ASTM F912 fastener standards. Installed by machinists, maintenance technicians, and mechanical assemblers in a wide range of industrial and OEM applications.

The half dog point geometry makes this set screw well-suited for use in shaft-to-hub connections, collars, and mechanical assemblies where the point must engage a mating hole or slot in the shaft to transmit torque or provide positive positioning. The partial dog point allows for easier alignment during installation compared to a full dog point. Typical applications include conveyor components, pulleys, gears, couplings, and general mechanical assemblies requiring a secure, non-slip connection between rotating or sliding parts.

Key Features

• Half dog point geometry for positive shaft engagement and alignment in mating holes or slots
• 1/4-20 UNC thread with 5/8-inch overall length
• Grade 8 alloy steel construction for high tensile and shear strength
• 1/8-inch hex socket drive compatible with standard hex keys and Allen drivers
• Conforms to ASME/ANSI B18.3 and ASTM F912 standards
• Fractional inch measurement, UNC thread standard

Compatibility

Designed as a standard 1/4-20 UNC half dog point set screw for use in any mechanical assembly requiring ASME/ANSI B18.3 or ASTM F912 compliant fasteners of this size and point type.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 1/8-inch hex key. Always ensure the mating component is properly aligned with the half dog point before tightening. Torque to the fastener manufacturer specification for Grade 8 alloy steel at this thread size. De-energize and lock out all rotating equipment before installing or removing set screws per applicable safety procedures.
