Value Collection D30091 Hex Head Cap Screw 7/16-14 X 4 in

Product Description

The VALUE COLLECTION D30091 is a Grade 5 steel hex head cap screw sized 7/16-14 x 4 inches, designed for general mechanical assembly in industrial, commercial, and trade applications. The partially threaded shank provides a bearing surface under the head, making it well suited for clamped-joint connections where full threading would reduce clamping force. The zinc-plated finish provides a base level of corrosion resistance for indoor and light-duty outdoor environments. This fastener follows Unified National Coarse (UNC) thread form and meets ASME B18.2.1 and SAE J429 dimensional and strength standards. Installers in HVAC, plumbing, electrical, and mechanical contracting use this screw class daily for equipment mounting, structural brackets, and panel assembly.

This hex head cap screw is appropriate for use in residential and light commercial mechanical systems wherever a 7/16-14 UNC fastener is specified. Typical applications include equipment base-rail attachment, fan-deck mounting, electrical panel brackets, and general structural hardware connections. The Grade 5 rating indicates a minimum tensile strength appropriate for medium-duty load-bearing joints. This screw is sold individually with a minimum order quantity of 10 units.

Key Features

• 7/16-14 UNC thread form for broad compatibility with standard tapped holes and nuts
• 4-inch length under head for use in thicker assemblies or stacked material applications
• Partially threaded shank maintains full clamping force across the joint interface
• Grade 5 steel meets SAE J429 tensile and proof-load requirements for medium-duty applications
• Zinc-plated finish resists surface oxidation in dry and low-humidity environments
• Conforms to ASME B18.2.1 for head dimensions and tolerances

Compatibility

Designed as a standard 7/16-14 UNC partially threaded hex head cap screw suitable for use with any tapped hole, hex nut, or coupling nut conforming to UNC thread standards at that diameter and pitch.

Installation Notes

Installation requires a standard 5/8-inch hex wrench or socket driver. Ensure mating threads are clean and free of debris before assembly. Apply thread lubricant or anti-seize compound if required by the application environment. Always torque to the value specified in the equipment or structural design documentation — do not substitute generic torque values.
