Value Collection 141022PR Set Screw 8-32 5/16in Half Dog

Product Description

The VALUE COLLECTION 141022PR is an 8-32 x 5/16-inch half dog point set screw manufactured from Grade 8 alloy steel. It features a 5/64-inch hex drive and is dimensioned to overall length. Set screws of this type are used to secure a component — such as a collar, gear, or pulley — against a shaft by applying clamping force at the point of contact. The half dog point provides a short cylindrical extension that seats into a drilled hole or flat on the shaft, resisting rotation and axial movement. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards and is suited for use in mechanical assemblies across industrial and trade applications.

This set screw is used in applications where a headless, flush-mount fastener is required and shaft positioning must be maintained under load. Typical installations include motor shaft collars, conveyor components, and equipment drives. The half dog point is preferred when the mating shaft has a pre-drilled locating hole, providing positive engagement versus a cup or cone point. It is well suited for both initial assembly and field service work on rotating mechanical equipment.

Key Features

• Half dog point provides positive shaft engagement in pre-drilled locating holes
• 5/64-inch hex drive accepts standard hex keys for installation and removal
• Grade 8 alloy steel construction for high tensile and torsional strength
• 8-32 UNC thread for compatibility with standard inch-series tapped holes
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Overall length of 5/16 inches suits compact assembly envelopes

Compatibility

Designed as a standard 8-32 UNC half dog point set screw for use in any application with a corresponding tapped hole and shaft or component requiring positional retention.

Installation Notes

Installation is performed with a 5/64-inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive. Power down and de-energize any equipment before servicing components that contain set screws. Confirm that the mating shaft has a properly sized and positioned locating hole when using a half dog point to achieve full engagement. Minimum order quantity of 100 pieces applies to this part.
