Value Collection MP40392 Set Screw 3/8-16 X 3/4 in Grade 8

Product Description

The VALUE COLLECTION MP40392 is a cup point set screw designed for mechanical fastening applications where a strong, recessed hold is required. Built from Grade 8 alloy steel, this screw delivers high tensile strength and hardness suitable for demanding industrial and mechanical assemblies. It features a 3/8-16 UNC thread and measures 3/4 inches in overall length. The 3/16-inch hex drive accepts a standard hex key for installation and adjustment. This fastener is manufactured to ASME/ANSI B18.3 and ASTM F912 standards and is sold in packs of 25, making it practical for shop stock or job-lot use. Machinists, millwrights, and maintenance mechanics are the typical installers.

Cup point set screws are commonly used to secure rotating components such as collars, pulleys, gears, and shafts in place. The cup point geometry bites into the shaft surface to resist rotation and axial movement. These fasteners are appropriate for light-to-heavy-duty mechanical assemblies in both production and field maintenance settings. This particular screw is suited to applications requiring a fully threaded, headless profile where flush or recessed installation is necessary.

Key Features

• Grade 8 alloy steel construction for high tensile strength and hardness
• Cup point geometry bites into shaft to resist rotation and axial movement
• 3/8-16 UNC thread for compatibility with standard tapped holes
• 3/16-inch hex drive for use with standard hex keys
• Meets ASME/ANSI B18.3 and ASTM F912 standards
• Sold in a pack of 25 for shop stock or batch use

Compatibility

Designed as an OEM-style replacement or stock fastener for any mechanical assembly requiring a 3/8-16 UNC cup point set screw with a 3/16-inch hex drive and 3/4-inch overall length.

Installation Notes

Installation is typically performed by machinists or maintenance mechanics using a 3/16-inch hex key. Ensure the tapped hole is clean and free of debris before threading the screw. Torque the fastener to the appropriate specification for Grade 8 alloy steel based on your assembly requirements. Confirm the shaft or mating surface is properly positioned before final tightening to prevent damage to the contact point.
