Value Collection B10081 Set Screw 8-32 X 5/16 in Half Dog Point

Product Description

The VALUE COLLECTION B10081 is an 8-32 x 5/16-inch half dog point set screw manufactured from Grade 8 alloy steel with a black oxide finish. 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 through a threaded hole, with no exposed head protruding beyond the mating surface. The hex drive allows installation with a standard hex key. The half dog point provides a short cylindrical tip that seats into a mating hole or flat on the shaft, preventing axial rotation and movement under load. Sold in a package of 100 pieces.

Half dog point set screws in 8-32 UNC thread are used across light mechanical assemblies, HVAC equipment, electrical enclosures, and general industrial applications where positive shaft location is required. The black oxide finish provides mild corrosion resistance in dry or low-humidity indoor environments. Grade 8 alloy steel construction delivers higher tensile and proof load ratings compared to standard Grade 2 or Grade 5 fasteners, making these suitable for higher-torque clamping applications within the 8-32 thread class.

Key Features

• Thread size 8-32 UNC for compatibility with standard inch-series threaded holes
• 5/16-inch overall length provides adequate engagement depth in typical light-duty assemblies
• Half dog point tip seats into a drilled locating hole or flat on the shaft for positive positioning
• Grade 8 alloy steel construction for higher clamping strength versus standard grades
• Black oxide finish for mild corrosion resistance in indoor environments
• Hex drive (internal) for installation with a standard hex key or hex-tip bit driver

Compatibility

Designed as a standard 8-32 UNC half dog point set screw suitable for general mechanical assemblies, light industrial equipment, and trade service applications requiring inch-series threaded fasteners with a locating-tip point style.

Installation Notes

Installation is typically performed by maintenance technicians or mechanical tradespeople using a properly sized hex key to avoid rounding the drive socket. Ensure the mating shaft has a correctly sized and positioned locating hole or flat that accepts the half dog point before tightening. De-energize and lock out any rotating or powered equipment before fastener installation or removal in accordance with applicable OSHA lockout/tagout procedures. Do not exceed the rated tightening torque for the 8-32 thread class and Grade 8 material as published in standard fastener references.
