Value Collection MP40348 Set Screw 10-24 3/16 in Grade 8 50pk

Product Description

The VALUE COLLECTION MP40348 is a cup point set screw designed for secure, mar-resistant clamping in mechanical assemblies. This fastener features a 10-24 UNC thread with an overall length of 3/16 inches and is driven by a 3/32-inch hex key. Manufactured from alloy steel to Grade 8 specifications, it delivers high tensile and torsional strength for demanding setscrew applications. Compliance with ASME/ANSI B18.3 and ASTM F912 standards confirms dimensional and performance consistency. Each package contains 50 pieces, making it a practical bench stock item for maintenance shops, production floors, and service vans.

Cup point set screws like the MP40348 are used across a wide range of trade and industrial applications. They are commonly driven into threaded bores to secure pulleys, collars, gears, and shafts against rotation or axial movement. The cup point digs lightly into the mating surface, providing reliable holding force without requiring a through-hole. Typical installations include HVAC blower assemblies, pump shaft collars, motor pulleys, and equipment panels where a headless fastener is required to sit flush or below the surface.

Key Features

• Cup point geometry bites into mating surface for positive grip without a bolt head
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 10-24 UNC thread for broad compatibility with standard tapped bores
• 3/16-inch overall length suits shallow-bore and thin-wall applications
• Driven with a 3/32-inch hex key — standard L-wrench or T-handle driver
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and performance standards
• Sold in a 50-piece package for shop stock and field kit replenishment

Compatibility

Designed for standard 10-24 UNC tapped bores requiring a headless cup point fastener in residential and commercial mechanical, HVAC, and industrial equipment assemblies.

Installation Notes

Installation is performed with a 3/32-inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. De-energize and lock out any rotating equipment before servicing collars, pulleys, or shaft-mounted components secured by set screws. Do not reuse a set screw that shows deformation of the cup point or drive socket, as reduced engagement can lead to fastener walkout under load.
