Value Collection R40660144 Hex Socket Cap Screw 5-40 Unc

Product Description

The VALUE COLLECTION R40660144 is a hex socket cap screw designed for fastening applications that require a compact drive interface and reliable clamping force in tight spaces. This screw uses a 3/32 inch internal hex drive and a 5-40 UNC thread form, with 1 inch of length measured under the head. It is manufactured from 18-8 stainless steel, which provides corrosion resistance suitable for both indoor and outdoor environments. Electricians, HVAC technicians, and mechanical tradespeople use socket cap screws like this one when a low-profile, high-strength fastener is needed in confined assemblies or equipment enclosures.

This fastener fits applications across light mechanical assemblies, electrical panel components, HVAC equipment housings, and general trade fabrication where a 5-40 UNC thread is specified. The fine thread pitch of the 5-40 UNC designation provides good resistance to loosening under vibration, making it appropriate for equipment subject to operational movement. It is sold individually but requires a minimum order quantity of 100 pieces per transaction, making it suited for contractors and shop stock replenishment rather than single-fastener replacement needs.

Key Features

• 5-40 UNC thread size with 1 inch length under head for precise fitment in standard tapped holes
• 3/32 inch internal hex drive accepts standard hex keys and ball-end drivers
• 18-8 stainless steel construction resists corrosion in humid or outdoor service environments
• Fine thread pitch improves resistance to vibration-induced loosening
• Low-profile socket cap head design suits recessed or flush-mount fastening applications

Compatibility

Designed as a standard 5-40 UNC hex socket cap screw for use in any application requiring that thread size and a 3/32 inch hex drive, including light mechanical assemblies, control enclosures, and equipment panels.

Installation Notes

Installation requires a 3/32 inch hex key or T-handle driver; a ball-end driver is useful when access angle is limited. Ensure the mating tapped hole is clean and the thread form matches 5-40 UNC before driving. De-energize any electrical equipment fully before working on enclosures or panels where these fasteners are used. Do not overtighten stainless steel fasteners in stainless tapped holes, as galling can occur; apply an appropriate anti-seize compound if the application permits.
