Value Collection R63263649 Set Screw 3/8-24 X 1/2in Cup Point

Product Description

The VALUE COLLECTION R63263649 is a 3/8-24 UNF cup point set screw machined from 18-8 stainless steel. It measures 1/2 inch in overall length and is driven by a 3/16-inch hex key. The cup point geometry bites into the mating shaft to resist rotation and axial movement without requiring a through-hole. This fastener is suited for mechanical assemblies where corrosion resistance is a priority, such as wet environments, food-service equipment, or marine-adjacent applications. Machinists, millwrights, and maintenance technicians are the typical installers.

This set screw is used in shaft collars, shaft couplings, pulleys, gears, and similar rotating or sliding mechanical components where a flush or recessed fastener is required. The 3/8-24 UNF thread provides finer thread engagement than a comparable UNC fastener, which improves clamping force control during torquing. The 18-8 stainless steel construction makes it appropriate for applications where carbon steel fasteners would corrode or contaminate the assembly.

Key Features

• Cup point geometry provides positive shaft engagement and resists axial and rotational movement
• 3/8-24 UNF thread for fine-pitch control during installation
• 18-8 stainless steel construction for corrosion resistance in wet or oxidizing environments
• 3/16-inch hex drive for use with standard Allen keys or hex-bit drivers
• 1/2-inch overall length fits typical shaft collar and coupling applications

Compatibility

Designed as an OEM-style replacement or standard fastener for any mechanical assembly requiring a 3/8-24 UNF cup point set screw driven by a 3/16-inch hex key.

Installation Notes

A licensed machinist or qualified maintenance technician should install this fastener using a properly sized 3/16-inch hex key or L-wrench to avoid rounding the drive socket. De-energize and lock out all rotating equipment before servicing any shaft-mounted component. Do not use with aluminum shafting without confirming surface hardness compatibility, as the cup point can embed into soft materials under high clamp loads. Apply a thread-locking compound only if specified by the equipment manufacturer.
