Value Collection MP40375 Set Screw 5/16-18 X 3/8 in Cup Point Gr8

Product Description

The VALUE COLLECTION MP40375 is a cup point set screw designed for mechanical assemblies where a fastener must apply clamping or locking force without protruding above a surface. Threaded 5/16-18 UNC with an overall length of 3/8 inches, this headless screw is driven with a 5/32-inch hex key and seats via its cup-shaped point to bite into a shaft or mating surface. Manufactured from Grade 8 alloy steel, it delivers the tensile strength required for demanding industrial and mechanical applications. Each package contains 50 pieces. Licensed machinists, millwrights, and maintenance technicians are the primary installers of this fastener type.

Cup point set screws in this thread size are widely used in shaft collars, pulleys, gears, sprockets, and other power-transmission components where controlled axial and rotational locking is needed. They are suitable for both light-duty and moderate-load mechanical assemblies across manufacturing, maintenance, and general industrial environments. The 5/16-18 UNC thread is a common standard in North American mechanical hardware, making this screw a straightforward replacement or stock item for MRO and production applications.

Key Features

• Cup point geometry bites into shaft material for secure locking without a protruding head
• 5/16-18 UNC thread for broad compatibility with standard tapped holes
• Grade 8 alloy steel construction provides high tensile and proof load strength
• 5/32-inch hex drive allows installation with a standard Allen key or hex bit driver
• Conforms to ASME/ANSI B18.3 and ASTM F912 fastener standards
• Sold in a 50-piece pack, suitable for stocking or project quantities

Compatibility

Designed as a standard 5/16-18 UNC cup point set screw for use in any tapped hole or component conforming to ASME/ANSI B18.3 dimensional requirements.

Installation Notes

Installation is performed with a 5/32-inch hex key or Allen driver. Ensure the mating tapped hole is clean and free of debris before threading in the screw. Apply appropriate thread-locking compound if vibration resistance is required. Do not exceed the torque capacity of the alloy steel material; refer to a standard Grade 8 fastener torque table for the correct value for this thread size.
