Value Collection 63601 Cup Point Set Screw 3/8-16 Grade 316

Product Description

The VALUE COLLECTION 63601 is a cup point set screw designed for secure, vibration-resistant fastening in mechanical assemblies. Manufactured from Grade 316 stainless steel, this fastener offers strong corrosion resistance, making it well-suited for wet, marine, chemical, or outdoor environments. The 3/8-16 UNC thread and 3/8-inch overall length suit a wide range of shaft and collar applications. A 3/16-inch hex drive key engages the socket for reliable torque transfer. This item is sold in a package quantity of 25, allowing technicians and maintenance professionals to stock up for repetitive installation tasks across multiple assemblies.

Cup point set screws like the 63601 are commonly installed in collars, pulleys, gears, sprockets, and hubs to lock components onto shafts. They are used across residential and light commercial mechanical systems, including HVAC equipment, pumps, and fan assemblies, wherever a recessed, flush-mount fastener is required. The cup point geometry bites into the shaft surface, providing a positive hold without requiring a separate locking element. Installation is performed by maintenance technicians and millwrights using a standard 3/16-inch hex key.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in harsh or wet environments
• Cup point tip bites into shaft surface for positive, vibration-resistant locking
• 3/8-16 UNC thread standard for broad compatibility with inch-measurement mechanical components
• 3/16-inch internal hex drive accepts standard Allen or hex key tools
• 3/8-inch overall length suits shallow-bore collar and hub applications
• Sold in a pack of 25 for jobsite and shop stocking convenience

Compatibility

Designed as a standard 3/8-16 UNC cup point set screw for use in any collar, hub, pulley, or mechanical assembly that accepts a 3/8-inch length set screw with a 3/16-inch hex drive.

Installation Notes

De-energize and lock out all equipment before installing or removing set screws on rotating shafts or assemblies. Use a properly sized 3/16-inch hex key to seat the fastener fully without rounding the drive socket. Do not overtighten, as excessive torque can damage the shaft or strip the thread. Verify thread engagement and cup point contact against the shaft before returning equipment to service.
