Value Collection D30033 Hex Head Cap Screw 5/16-18x2 Grade 5

Product Description

The VALUE COLLECTION D30033 is a 5/16-18 x 2 inch hex head cap screw designed for general mechanical fastening in trade and industrial applications. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener delivers solid tensile strength and basic corrosion resistance suited to indoor and sheltered outdoor environments. The screw is partially threaded with a unified coarse (UNC) thread form and meets ASME B18.2.1 dimensional standards. It is driven with a standard hex wrench or socket and is installed by millwrights, HVAC mechanics, plumbers, electricians, and general tradespeople wherever a reliable 5/16-18 threaded fastener is required.

This cap screw is appropriate for light structural connections, equipment mounting, panel attachment, bracket installation, and general mechanical assembly across residential and commercial trade work. The 2 inch length under head accommodates moderate material stack-ups, while the partial threading engages mating threads cleanly without bottoming out in blind holes. It is sold in multiples of 25, making it practical for repetitive fastening tasks on job sites or in shop environments.

Key Features

• 5/16-18 UNC thread form — broad compatibility with standard tapped holes and hex nuts
• Grade 5 steel construction provides improved tensile strength over Grade 2 fasteners
• Zinc-plated finish offers basic corrosion resistance for indoor and sheltered applications
• Partially threaded shank reduces thread engagement stress and suits through-bolt applications
• Meets ASME B18.2.1 dimensional standards for consistent fit and interchangeability
• Hex head drive accepts standard sockets and wrenches — no special tooling required

Compatibility

Designed as a standard 5/16-18 UNC hex head cap screw suitable for use with any mating 5/16-18 nut or tapped hole conforming to UNC thread standards.

Installation Notes

Installation does not require specialized trade licensing but should follow applicable mechanical codes and equipment manufacturer torque specifications. Always ensure the mating hole or nut is the correct thread size and pitch before driving. Use a properly sized hex socket or wrench to avoid rounding the head. Do not exceed the rated load capacity of Grade 5 fasteners in high-stress or safety-critical structural connections where Grade 8 hardware may be required.
