Value Collection 141173PR Set Screw 3/8-24 X 3/8 in Half Dog Point

Product Description

The VALUE COLLECTION 141173PR is a Grade 8 alloy steel set screw designed for secure, flush or recessed fastening in mechanical assemblies. Threaded 3/8-24 UNF with an overall length of 3/8 inches, this fastener features a half dog point that provides positive axial location against a mating part, preventing rotation or axial shift under load. It is driven with a 3/16-inch hex key and conforms to ASME/ANSI B18.3 and ASTM F912 standards. Grade 8 alloy steel construction delivers the high tensile strength required in demanding industrial and mechanical applications.

This set screw is suited for use in shaft collars, shaft couplings, pulleys, sprockets, and similar rotating or sliding component assemblies where a captive dog point is needed for positive location. Typical applications span industrial machinery, power transmission assemblies, and precision mechanical fixtures. The half dog point design engages a mating drilled recess, making it a dependable choice when the fastener must align or hold a mating component at a fixed position.

Key Features

• Half dog point provides positive axial location in drilled mating holes
• Grade 8 alloy steel for high tensile strength and durability
• 3/8-24 UNF thread for fine-pitch, vibration-resistant engagement
• 3/16-inch hex drive per ASME/ANSI B18.3 standard
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Compact 3/8-inch overall length suits tight assembly clearances

Compatibility

Designed as an OEM-style replacement or maintenance-stock fastener for mechanical assemblies requiring a 3/8-24 UNF half dog point set screw with a 3/16-inch hex drive.

Installation Notes

Installation is typically performed by millwrights, machine technicians, or maintenance mechanics using a 3/16-inch hex key or Allen wrench. De-energize and lock out all rotating equipment before installing or removing set screws. Do not exceed the torque rating appropriate for Grade 8 alloy steel at this thread size as specified by the equipment manufacturer. Minimum order quantity is 100 pieces per order.
