Value Collection D30070 Hex Head Cap Screw 3/8-16 X 6 in

Product Description

The VALUE COLLECTION D30070 is a partially threaded hex head cap screw designed for general-purpose fastening applications in mechanical, structural, and equipment assembly work. Sized at 3/8-16 thread with a 6-inch length under head, this fastener meets ASME B18.2.1 dimensional standards for inch-series hex head cap screws. The Grade 5 steel construction provides reliable tensile strength for medium-duty bolted connections, and the zinc-plated finish adds a layer of corrosion resistance for use in typical indoor and light industrial environments. The UNC (Unified National Coarse) thread form is the standard for most domestic fastener applications.

This screw is suited for use in fabrication shops, equipment maintenance, HVAC unit assembly, plumbing equipment mounting, and general mechanical work where a 3/8-16 UNC partially threaded fastener is specified. Partial threading allows for greater grip in bolted joint applications where the unthreaded shank bears load across the joint interface. Trades including millwrights, HVAC technicians, pipefitters, and general maintenance mechanics regularly work with fasteners of this specification.

Key Features

• 3/8-16 UNC thread, 6-inch length under head for deep fastening applications
• Grade 5 steel construction for medium-duty tensile load requirements
• Zinc-plated finish for corrosion resistance in standard service environments
• Partially threaded shank per ASME B18.2.1 dimensional standard
• Inch measurement system with UNC thread standard for broad domestic compatibility

Compatibility

Designed as a standard inch-series hex head cap screw for any application specifying a 3/8-16 UNC partially threaded fastener per ASME B18.2.1.

Installation Notes

Install using a standard hex wrench or socket driver sized for a 3/8-inch hex head cap screw. Ensure mating threads are clean and free of debris before installation. Follow applicable torque specifications from the equipment manufacturer or relevant structural standards for Grade 5 fasteners. Minimum order quantity for this item is 10 units.
