Value Collection 403286BR Hex Head Cap Screw 3/4-10 X 4.5 in

Product Description

The VALUE COLLECTION 403286BR is a partially threaded hex head cap screw designed for general-purpose fastening in mechanical, structural, and trade assembly applications. It features a 3/4-10 UNC thread and measures 4.5 inches under the head. Constructed from Grade 2 steel with a zinc-plated finish, it provides basic corrosion resistance suitable for interior and light exterior environments. The partial threading allows for clamping force between mating surfaces without thread engagement along the full shank length. This fastener is installed using a 1-1/8 inch hex wrench or socket and is commonly turned by HVAC technicians, plumbers, electricians, and general maintenance trades during equipment assembly and structural attachment work.

This cap screw is suited for residential and light commercial applications where a standard-strength, inch-series fastener is required. Typical uses include equipment mounting, bracket attachment, and general mechanical assembly. The 3/4-10 UNC thread is one of the most common coarse-thread sizes in inch-standard fastener work, making this screw a practical stock item for service vehicles and shop inventory alike.

Compatibility

Designed for use with standard 3/4-10 UNC inch-series nuts, washers, and threaded components in general mechanical and trade assembly applications.

Installation Notes

Installation is performed with a 1-1/8 inch socket or open-end wrench. Always confirm thread engagement before applying torque to avoid cross-threading. Use appropriate flat washers or lock washers per the assembly specification. Follow applicable mechanical codes and equipment manufacturer guidelines when fastening structural or pressure-bearing components.
