Value Collection 88548995 Hex Cap Screw 1/2-13 X 3 in Grade 5

Product Description

The VALUE COLLECTION 88548995 is a 1/2-13 x 3-inch hex head cap screw designed for general fastening applications across mechanical, structural, and trade installation work. The fastener features a partially threaded shank with Unified National Coarse (UNC) thread standards, Grade 5 steel construction, and a zinc-plated finish for basic corrosion resistance. Length is measured under the head at 3 inches. At just under 0.2 pounds per piece, it is sized for medium-duty bolted connections where a standard hex drive and reliable clamping load are required. HVAC, plumbing, and electrical installers commonly use this fastener series for equipment mounting and structural bracketing.

This screw is suited for residential and light commercial installation scenarios where inch-measurement UNC hardware is specified. It is a fit for equipment bases, support frames, junction boxes, and general mechanical assemblies. The partial thread design allows for greater shank strength and improved clamping in thicker material stacks. This item is packaged in a quantity of 3 per pack with a minimum order of 1 pack.

Key Features

• Grade 5 steel construction for reliable tensile and yield strength in medium-duty applications
• Zinc-plated finish provides basic corrosion protection in dry and mildly humid environments
• Partially threaded shank improves clamping load and shear strength in thicker material
• UNC thread standard ensures compatibility with standard 1/2-13 nuts and tapped holes
• 3-inch length under head accommodates multi-layer assemblies and heavy flanges
• Packaged in quantities of 3 per pack with no minimum beyond 1 pack

Compatibility

Designed as a standard inch-series UNC replacement or service fastener compatible with any 1/2-13 threaded nut, insert, or tapped hole conforming to Unified National Coarse thread standards.

Installation Notes

Installation should be performed by a qualified mechanic or trade technician using a standard hex socket or open-end wrench sized for a 1/2-inch bolt head. De-energize and isolate any equipment before fastening or replacing hardware on live systems. Follow applicable code requirements such as NEC or IFGC for fastener placement on electrical or gas equipment enclosures. Do not use impact tools without a torque-limiting setting, as over-driving can damage threads or reduce clamping integrity.
