Value Collection 131127PR Set Screw 5/16-18 X 5/16 in Oval Point

Product Description

The VALUE COLLECTION 131127PR is a 5/16-18 x 5/16 inch oval point set screw manufactured from Grade 8 alloy steel. Set screws of this type are fully threaded fasteners with no head, designed to be driven flush with or below the surface of a mating part to secure a component — such as a pulley, collar, or gear — against rotation or axial movement on a shaft. The 5/32 inch internal hex drive accepts a standard hex key for installation and removal. This screw meets ASME/ANSI B18.3 and ASTM F912 standards and is suited for mechanical assemblies requiring a high-strength, compact fastening solution.

Oval point set screws are used where a moderate level of shaft penetration and holding power is needed without the marring associated with a cup or cone point. Typical applications include machine tools, motors, conveyor components, and other rotating shaft assemblies found in industrial and commercial mechanical environments. The UNC thread standard and fractional inch sizing make this fastener compatible with standard imperial-threaded components. These are installed by machinists and mechanical technicians as part of power transmission and rotating assembly work.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength
• Oval point geometry provides moderate shaft penetration and reduced surface marring
• 5/32 inch hex drive accepts standard hex keys and hex-key bits
• UNC thread standard for compatibility with standard imperial-threaded bores
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Compact 5/16 inch overall length suits tight-clearance assemblies

Compatibility

Designed as a standard UNC imperial set screw for use in threaded bores sized 5/16-18. Suitable for use in pulleys, shaft collars, couplings, and similar power transmission components that accept a 5/16-18 threaded set screw with an oval point.

Installation Notes

Set screws of this type are installed by machinists or mechanical technicians using a 5/32 inch hex key or hex-key driver bit. De-energize and lock out all equipment before servicing any rotating assembly. Apply thread-locking compound if vibration or dynamic loading is present in the application. Do not exceed the rated seating torque for the thread size and grade as specified by applicable fastener standards.
