Value Collection D30116 Hex Head Cap Screw 1/2-13 X 4 in

Product Description

The VALUE COLLECTION D30116 is a partially threaded hex head cap screw sized at 1/2-13 x 4 inches, manufactured from Grade 5 steel with a zinc-plated finish. The 1/2-13 designation refers to a half-inch nominal diameter with 13 threads per inch on a Unified National Coarse (UNC) thread form. Zinc plating provides a baseline level of corrosion resistance suited to general indoor and sheltered outdoor applications. This fastener conforms to ASME B18.2.1 dimensional standards, making it a direct fit for applications that call out that specification. Tradespeople across HVAC, plumbing, electrical, and general mechanical assembly use this screw for equipment mounting, structural connections, and panel fastening.

This cap screw is appropriate for light to medium structural fastening tasks in residential and commercial trade work. The partial threading leaves a smooth shank near the head, which is preferred in applications where the fastener passes through a clearance hole before engaging a tapped hole or nut. Typical uses include equipment base mounting, bracket attachment, and general mechanical assembly where an inch-series UNC fastener is specified. It is sold in a minimum order quantity of 10 units.

Key Features

• 1/2-13 UNC thread form, partially threaded for clearance-hole applications
• 4-inch length measured under the head per ASME B18.2.1
• Grade 5 steel construction for medium-strength fastening requirements
• Zinc-plated finish for basic corrosion resistance in general service environments
• Conforms to ASME B18.2.1 dimensional standard

Compatibility

Designed as a standard inch-series UNC hex head cap screw for general mechanical and trade assembly applications requiring a 1/2-13 x 4-inch Grade 5 fastener per ASME B18.2.1.

Installation Notes

Installation is performed with a standard hex wrench or socket driver sized for a 1/2-13 hex head. Ensure the mating hole is properly sized and tapped or paired with an appropriate nut before driving. Do not exceed the torque rating appropriate for Grade 5 steel at this thread size per applicable project specifications. De-energize and isolate any equipment before fastening components to live assemblies.
