Value Collection 141150PR Set Screw 5/16-24 X 3/8 in Half Dog

Product Description

The VALUE COLLECTION 141150PR is a half dog point set screw designed for mechanical assemblies requiring a positive locating point against a mating shaft or component. The screw measures 5/16-24 (UNF) thread with an overall length of 3/8 inches and is driven by a 5/32 inch hex key. Manufactured from Grade 8 alloy steel, it delivers high tensile and torsional strength for demanding industrial and mechanical applications. This fastener conforms to ASME/ANSI B18.3 and ASTM F912 standards, making it a code-compliant choice for engineers, millwrights, and maintenance technicians working on shaft collars, couplings, and rotating equipment.

Half dog point set screws like the 141150PR are commonly used where the point must seat into a drilled or machined flat on a shaft to resist axial and rotational movement. Typical install scenarios include motor shaft collars, pulley hubs, gear assemblies, and positioning fixtures in both light industrial and heavy mechanical environments. The UNF thread form is suited for applications where fine thread engagement provides greater holding power in the radial direction. Sold individually per package with a minimum order quantity of 100 pieces.

Key Features

• Half dog point geometry seats into a drilled or milled flat on a shaft for positive axial and rotational location
• Grade 8 alloy steel construction provides high tensile strength for demanding mechanical service
• 5/16-24 UNF thread form offers fine-pitch engagement for increased clamping force
• 5/32 inch hex drive accepts standard hex keys and Allen-type drivers
• Compliant with ASME/ANSI B18.3 and ASTM F912 fastener standards
• Compact 3/8 inch overall length suits tight clearance installations

Compatibility

Designed as a standard ASME/ANSI B18.3 half dog point set screw for use in any application requiring a 5/16-24 UNF threaded socket set screw with a half dog point and 5/32 inch hex drive.

Installation Notes

Installation is typically performed by millwrights, maintenance mechanics, or assembly technicians using a 5/32 inch hex key or Allen driver. Ensure the mating shaft has a properly sized drilled flat or indent to receive the dog point before tightening. De-energize and lock out any rotating equipment before servicing components secured by set screws. Avoid exceeding the fastener's rated torque capacity, and inspect threads for damage before installation to ensure full engagement.
