Value Collection 141055PR Set Screw 10-24 3/8 in Half Dog

Product Description

The VALUE COLLECTION 141055PR is a 10-24 UNC alloy steel set screw with a half dog point, designed for secure fastening applications where a protruding point is needed to locate or retain a mating component. Measuring 3/8 inches in overall length, this Grade 8 fastener is driven by a 3/32-inch hex key and meets ASME/ANSI B18.3 and ASTM F912 standards. The half dog point provides a short cylindrical extension beyond the thread that seats into a drilled hole or slot, resisting shaft rotation or axial movement without damaging the shaft surface the way a cup or cone point would.

This set screw is suited for use in mechanical assemblies, power transmission components, and light industrial equipment where a #10-24 threaded hole is specified. Typical applications include collars, hubs, pulleys, and shaft-mounted components in manufacturing, maintenance, and machine-shop environments. Machinists, millwrights, and maintenance technicians commonly install this fastener when building or servicing rotating assemblies that require a positive locating feature. This screw is sold in minimum order quantities of 100 pieces per order.

Key Features

• Half dog point provides a cylindrical locating tip that seats into a mating hole or slot without marring the shaft
• Grade 8 alloy steel construction delivers high tensile and torsional strength for demanding clamping loads
• 10-24 UNC thread form ensures broad compatibility with standard inch-series tapped holes
• 3/32-inch internal hex drive for use with standard hex keys or Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards for dimensional and mechanical compliance
• Compact 3/8-inch overall length suits confined or thin-walled assemblies

Compatibility

Designed as a standard inch-series set screw for use in any threaded hole or component specified for a 10-24 UNC thread with a half dog point fastener per ASME/ANSI B18.3.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 3/32-inch hex key. Ensure the mating shaft or component has a properly drilled and deburred locating hole sized for the half dog point before driving the screw. Do not overtighten, as excessive torque can strip the small hex socket or damage the threaded hole in softer materials. Always de-energize and lock out rotating equipment before servicing any shaft-mounted fasteners.
