Value Collection 30109 Hex Head Cap Screw 1/2-13 X 2-1/4 in 25pk

Product Description

The VALUE COLLECTION 30109 is a 1/2-13 x 2-1/4 inch hex head cap screw manufactured from Grade 5 steel with a zinc-plated finish. The fastener features partial threading along the shank and a unified national coarse (UNC) thread form, conforming to ASME B18.2.1 dimensional standards. It is used across mechanical, structural, and equipment assembly applications where a reliable, code-recognized fastener is required. Trades including HVAC, plumbing, and general mechanical contractors regularly stock this size for equipment mounting, bracket installation, and structural connections.

This screw is suited for residential and light commercial applications where a 1/2-13 UNC threaded connection is specified. The partial thread design provides a smooth shank section between the bearing surface and the threaded portion, which is useful in applications requiring fastener alignment or where the shank passes through a clearance hole before engaging a tapped bore or nut. Sold in packs of 25, this fastener is appropriate for job-site stocking or small-batch assembly work.

Key Features

• 1/2-13 UNC thread size with 2-1/4 inch length under head
• Grade 5 steel construction for reliable mechanical strength
• Zinc-plated finish provides basic corrosion resistance in dry and low-moisture environments
• Partially threaded shank for clearance-hole and alignment applications
• Conforms to ASME B18.2.1 dimensional standard
• Sold in a pack of 25 for efficient stocking

Compatibility

Designed as a standard 1/2-13 UNC hex head cap screw per ASME B18.2.1, suitable for use with any standard 1/2-13 UNC tapped hole or nut in steel, aluminum, or similar structural assemblies.

Installation Notes

Installation is performed by mechanical and general trades using standard hex wrenches or socket sets sized for a 3/4-inch hex drive. Ensure mating threads are clean and free of debris before installation. Do not exceed the rated proof load for Grade 5 hardware; consult applicable structural or equipment specifications for torque requirements. Zinc plating provides limited corrosion resistance and is not recommended for direct outdoor exposure or high-humidity environments without additional protection.
