Value Collection R40666438 Hex Socket Cap Screw 6-32 Unc

Product Description

The VALUE COLLECTION R40666438 is a hex socket cap screw designed for secure, low-profile fastening in threaded assemblies. Sized at 6-32 UNC with a 3/4-inch length under head, this fastener is driven by a 7/64-inch hex key. Constructed from 18-8 stainless steel, it offers corrosion resistance suitable for use in humid, wet, or mildly chemical environments. The socket cap head style provides a clean profile and allows fastening in recessed or tight-clearance locations where a standard hex head wrench cannot fit. Machinists, millwrights, HVAC technicians, and general tradespeople routinely use this screw for equipment panel assembly, bracket mounting, and mechanical component attachment.

This screw is suited for light-duty mechanical assemblies across residential and commercial applications. Common use cases include securing access panels, mounting brackets, control board enclosures, and structural sub-assemblies in HVAC equipment, electrical panels, and general fabrication. The 6-32 UNC thread is a standard unified coarse pitch used widely in sheet metal and machined-part fastening. The 18-8 stainless steel grade makes it appropriate for indoor or outdoor installations where mild corrosion resistance is required.

Key Features

• 6-32 UNC thread for compatibility with standard unified coarse-threaded holes
• 3/4-inch length under head for typical panel and bracket fastening depth
• 7/64-inch hex socket drive for precise torque application in tight spaces
• 18-8 stainless steel construction for corrosion resistance in wet or humid environments
• Socket cap head style allows use in recessed or low-clearance fastening locations

Compatibility

Designed as a standard 6-32 UNC hex socket cap screw for use in any application requiring a unified coarse-threaded fastener with a 3/4-inch length under head and a 7/64-inch hex drive.

Installation Notes

Installation requires a 7/64-inch hex key or Allen driver. Ensure the mating threaded hole or nut is clean and free of debris before fastening. In stainless steel applications, apply an anti-seize compound to reduce the risk of thread galling during installation. Always power down or de-energize equipment before accessing internal panels or components that require fastener removal.
