Value Collection 015147PR Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 015147PR is a hex socket cap screw designed for fastening applications requiring a strong, compact drive interface. With a 1/4-20 UNC thread and a 5/8-inch length under the head, this screw is fully threaded from the bearing surface to the tip. The 3/16-inch hex drive accepts a standard hex key or Allen wrench. Constructed from alloy steel with a black oxide finish, the 015147PR provides good mechanical strength and moderate corrosion resistance in indoor and light-duty service environments. It is installed by maintenance technicians, pipefitters, electricians, and HVAC mechanics wherever a low-profile socket drive fastener is needed.

This screw is suited for general mechanical assembly, equipment mounting, and panel or bracket fastening in residential and light commercial trade applications. The 1/4-20 UNC thread is one of the most common coarse-thread fastener sizes in North American equipment, making this screw a practical stock item for service vans, maintenance shops, and job-site tool bags. The black oxide coating blends into dark-painted enclosures and reduces light reflection in finished assemblies.

Key Features

• Fully threaded shank provides maximum thread engagement over the full 5/8-inch length under head
• 3/16-inch hex socket drive accepts standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 mechanical requirements for socket cap screws
• Black oxide finish provides light corrosion resistance and a clean, low-glare appearance
• Conforms to ASME/ANSI B18.3 and IFI 124 dimensional standards

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any tapped hole or threaded insert meeting ASME/ANSI B18.3 dimensional requirements for this thread size and drive specification.

Installation Notes

Installation requires a 3/16-inch hex key or Allen bit driver. Ensure the mating tapped hole or nut is clean and free of debris before driving. De-energize or lock out any equipment before accessing fasteners on electrical enclosures or HVAC panels, following applicable NFPA 70E or equipment-specific lockout/tagout procedures. Do not exceed the rated mechanical load for the screw grade when torquing into thin-walled or soft-material tapped holes.
