Value Collection R40662409 Hex Socket Cap Screw 3-48 Unc

Product Description

The VALUE COLLECTION R40662409 is a hex socket cap screw designed for applications requiring a compact, high-strength threaded fastener. Threaded to 3-48 UNC specifications, it features a 5/64 inch internal hex drive and a length under head of 0.5 inches. The fastener is manufactured from 18-8 stainless steel, providing corrosion resistance suitable for both indoor and outdoor environments. It is installed using a standard hex key or Allen wrench and is commonly used by millwrights, maintenance technicians, and mechanical assembly professionals working with small-diameter threaded connections.

This screw is suited for light mechanical assemblies, instrument panels, equipment enclosures, and precision hardware applications where a clean, low-profile fastener head is required. The 3-48 UNC thread form is a fine-pitch coarse unified national thread used in small fastener applications common in HVAC controls, electrical enclosures, and light industrial equipment. Sold individually, with a minimum order quantity of 100 pieces.

Key Features

• 3-48 UNC thread specification for small-diameter fastener applications
• 5/64 inch hex socket drive accepts standard Allen or hex key tools
• 0.5 inch length under head for shallow to moderate material thickness
• 18-8 stainless steel construction for corrosion resistance
• Low-profile socket cap head design for flush or recessed installations

Compatibility

Designed as a standard 3-48 UNC hex socket cap screw suitable for mechanical assemblies, instrument hardware, and equipment enclosures that require a small-diameter stainless fastener with a hex socket drive.

Installation Notes

Installation requires a 5/64 inch hex key or Allen wrench sized to the socket drive. Ensure the mating threaded hole or nut is correctly tapped to 3-48 UNC before installation to avoid cross-threading. De-energize or power down any equipment before fastener service on electrical or control enclosures. Do not over-torque small-diameter fasteners, as stainless steel is susceptible to galling without proper lubrication.
