Value Collection 141169PR Set Screw 3/8-16 X 1 in Half Dog

Product Description

The VALUE COLLECTION 141169PR is a Grade 8 alloy steel set screw designed for high-strength fastening applications where a flush or recessed installation is required. The half dog point provides a reduced-diameter tip that locates into a mating hole or groove on a shaft, resisting rotational movement under load. Measuring 3/8-16 thread size by 1 inch in overall length, this fastener is driven with a 3/16-inch hex key. It meets ASME/ANSI B18.3 and ASTM F912 standards, making it a reliable choice for mechanical assemblies, tooling, and industrial equipment. Licensed machinists, millwrights, and maintenance mechanics are the typical installers.

This set screw is suited for shaft-to-hub connections, collar positioning, and similar mechanical retention tasks found in industrial machinery, conveyor systems, rotating equipment, and general fabrication. The half dog point style is commonly chosen when a permanent or semi-permanent location point in the mating part is acceptable. The UNC thread form ensures broad compatibility with standard inch-series tapped holes. Minimum order quantity is 100 pieces per order.

Key Features

• Half dog point tip locates into a drilled hole or groove on a mating shaft for positive retention
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 3/8-16 UNC thread form for compatibility with standard inch-series tapped holes
• 3/16-inch hex drive for use with standard hex keys or Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and performance standards
• 1-inch overall length suitable for moderate-depth engagement requirements

Compatibility

Designed for use in any application requiring a 3/8-16 UNC tapped hole set screw with a half dog point and 1-inch overall length in Grade 8 alloy steel.

Installation Notes

Installation is performed by threading the set screw into a pre-tapped 3/8-16 UNC hole using a 3/16-inch hex key. Ensure the mating shaft or component has a properly sized and positioned dog point hole or groove before fully seating the fastener. Always de-energize and lock out rotating equipment before servicing shaft-mounted components. Do not exceed the torque capacity appropriate for Grade 8 alloy steel fasteners of this thread size as specified in applicable mechanical standards.
