Value Collection D30059 Hex Head Cap Screw 3/8-16

Product Description

The VALUE COLLECTION D30059 is a 3/8-16 partially threaded hex head cap screw manufactured from Grade 5 steel with a zinc-plated finish. It measures 2.25 inches under the head and conforms to ASME B18.2.1 dimensional standards. The unified coarse (UNC) thread pattern and hex drive head make it a standard fastener for structural and mechanical assemblies across industrial, HVAC, plumbing, and general trade applications. The zinc-plated coating provides basic corrosion resistance suitable for indoor and light-duty outdoor use. Installation requires a standard hex wrench or socket set. This fastener is sold individually with a minimum order quantity of 25 pieces.

This cap screw is suited for general mechanical assemblies, equipment mounting, and structural connections where a Grade 5 steel fastener meets the required load rating. It is appropriate for use in residential and light commercial equipment installations including HVAC unit mounting, electrical panel brackets, plumbing fixture supports, and similar trade work requiring a 3/8-16 UNC threaded fastener with partial threading along the shank.

Key Features

• 3/8-16 UNC thread size with 2.25-inch length under head
• Partially threaded shank per ASME B18.2.1 standard
• Grade 5 steel construction for medium-strength applications
• Zinc-plated finish for basic corrosion resistance
• Hex head drive compatible with standard sockets and wrenches
• Inch measurement system with UNC thread standard

Compatibility

Designed as a standard 3/8-16 UNC hex head cap screw for use in any application requiring an ASME B18.2.1-compliant Grade 5 steel fastener of this size.

Installation Notes

Installation is performed with a standard hex socket or open-end wrench sized for a 3/8-16 fastener. Power down or de-energize any equipment before fastening components in electrical or HVAC assemblies. Do not exceed the rated load capacity of a Grade 5 fastener in high-stress or safety-critical structural joints without engineering review. Follow applicable codes and equipment manufacturer torque guidelines for the specific assembly.
