Value Collection 403170PR Hex Head Cap Screw 7/16-14 X 5 in

Product Description

The VALUE COLLECTION 403170PR is a 7/16-14 UNC hex head cap screw designed for general-purpose mechanical fastening in a wide range of trade and industrial applications. The fastener measures 5 inches under the head and features partial threading, which helps draw clamped components together tightly without thread engagement through the full length of the grip. Constructed from Grade 2 steel with a zinc-plated finish, it offers moderate corrosion resistance suited to indoor and protected outdoor environments. A licensed plumber, HVAC technician, electrician, or general contractor will encounter this fastener in equipment mounting, panel assembly, and structural bracketing tasks.

This cap screw is appropriate for light- to medium-duty bolted connections in residential and commercial construction and mechanical service work. The 7/16-14 UNC thread standard is widely used across HVAC equipment frames, electrical enclosure hardware, plumbing supports, and general mechanical assemblies. The zinc plating makes it a practical choice where mild corrosion protection is needed without the cost of stainless or hot-dip galvanized hardware. Minimum order quantity is 25 pieces; package quantity is 1.

Key Features

• 7/16-14 UNC thread size for broad compatibility with standard inch-series nuts and tapped holes
• 5-inch length under head accommodates thicker clamped stacks or extended grip lengths
• Partial threading allows full clamping force across the unthreaded shank section
• Grade 2 steel construction suitable for light- to medium-duty fastening loads
• Zinc-plated finish provides moderate corrosion protection in dry or semi-protected environments
• 5/8-inch hex key size compatible with standard 5/8-inch wrenches and sockets

Compatibility

Designed as a standard inch-series UNC hex head cap screw compatible with any 7/16-14 tapped hole or hex nut following ASME B18.2.1 dimensional standards.

Installation Notes

Install using a 5/8-inch open-end, box, or socket wrench; power-tool installation is acceptable with a torque-limiting clutch to avoid over-driving Grade 2 fasteners. De-energize and lock out equipment before replacing fasteners on electrical enclosures or HVAC unit frames per OSHA lockout/tagout requirements. Inspect mating threads for damage or debris before installation to ensure full thread engagement. Do not substitute Grade 2 hardware in joints specified for Grade 5 or Grade 8 fasteners.
