Value Collection D30002 Hex Head Cap Screw 1/4-20 X 3/4 in

Product Description

The VALUE COLLECTION D30002 is a 1/4-20 x 3/4 inch hex head cap screw manufactured from Grade 5 steel with a zinc-plated finish. Fully threaded with a Unified National Coarse (UNC) thread form, it meets ASME B18.2.1 dimensional standards. This fastener is suited for general mechanical assembly, equipment maintenance, and structural connection work across HVAC, plumbing, electrical, and general industrial applications. The zinc plating provides a baseline level of corrosion resistance for indoor and light-duty outdoor use. Installation requires a standard hex wrench or socket.

This screw is appropriate for light to medium-duty fastening applications in residential and commercial mechanical systems. It is commonly used when securing equipment panels, brackets, junction boxes, pipe hangers, and similar assemblies where a 1/4-20 threaded connection is specified. The 3/4 inch length under head and full thread engagement make it well suited for thin-to-medium material stacks without the need for a nut on a tapped hole.

Key Features

• Grade 5 steel construction for reliable tensile strength in general mechanical fastening
• Zinc-plated finish provides corrosion resistance for standard indoor and light-duty environments
• Fully threaded shaft allows maximum thread engagement across the full grip length
• 1/4-20 UNC thread form is among the most common sizes in trade mechanical assemblies
• Conforms to ASME B18.2.1 dimensional standards for interchangeability and consistency

Compatibility

Designed as a standard 1/4-20 UNC hex head cap screw suitable for use in any application specifying a 1/4-20 x 3/4 inch Grade 5 fully threaded hex fastener per ASME B18.2.1.

Installation Notes

Installation is performed with a standard hex socket or open-end wrench sized for a 1/4 inch hex head cap screw. Verify that the receiving hole is properly tapped to 1/4-20 UNC before driving the fastener. Do not overtighten, as Grade 5 fasteners at this diameter have defined proof load limits. Follow applicable equipment service documentation and relevant codes such as the NEC or IFGC when used in electrical or gas equipment assemblies.
