Value Collection 88549050 Hex Cap Screw 9/16-12 X 3 in Grade 5

Product Description

The VALUE COLLECTION 88549050 is a 9/16-12 x 3-inch hex head cap screw manufactured from Grade 5 steel with a zinc-plated finish. It features partial threading along the shank, which provides a smooth unthreaded grip section beneath the head — useful in applications requiring precise alignment or clamping without thread engagement along the full length of the fastener. This screw follows the Unified National Coarse (UNC) thread standard and is measured under the head at 3 inches. It is supplied in a package of 3 units. Mechanical contractors, millwrights, equipment technicians, and maintenance tradespeople commonly install this type of fastener in structural and general mechanical assemblies.

This fastener is suited for general industrial and mechanical applications where a medium-strength, inch-series hex cap screw is required. Typical uses include machine frames, equipment mounting, bracket attachment, and structural connections in both shop fabrication and field installation environments. The zinc coating provides baseline corrosion resistance appropriate for indoor and light-exposure applications. The 9/16-12 UNC thread size is a common coarse-pitch size found across a wide range of standard hardware and OEM equipment assemblies.

Key Features

• 9/16-12 UNC thread — standard coarse pitch for broad hardware compatibility
• 3-inch length measured under head — suits medium-depth through-fastening applications
• Grade 5 steel construction — meets medium-strength fastener requirements per SAE standards
• Zinc-plated finish — provides baseline corrosion resistance for indoor and light-duty environments
• Partially threaded shank — allows unthreaded grip section for alignment and clamping applications
• Packaged in quantity of 3 — suitable for single-use service calls or small-batch installations

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 9/16-12 UNC partially threaded fastener; fits standard 9/16-inch hardware, tooling, and equipment that accepts UNC coarse-thread fasteners.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician using an appropriate hex wrench, socket, or box-end wrench sized for a 9/16-12 hex head. Verify correct hole thread engagement before torquing to avoid cross-threading. Do not exceed the torque rating appropriate for Grade 5 fasteners at this diameter — consult applicable fastener torque charts for the specific joint material and lubrication condition. Zinc-plated fasteners should not be used in environments with continuous moisture exposure or chemical contact without additional corrosion protection measures.
