Value Collection D30105 Hex Head Cap Screw 1/2-13

Product Description

The VALUE COLLECTION D30105 is a fully threaded hex head cap screw sized 1/2-13 x 1-1/4 inches, manufactured from Grade 5 steel with a zinc-plated finish. This fastener follows the UNC thread standard and meets ASME B18.2.1 dimensional requirements, making it a reliable choice for general mechanical assembly and structural fastening applications. The zinc plating provides a basic level of corrosion resistance suitable for interior and light-duty environments. Electricians, plumbers, HVAC technicians, and general contractors commonly reach for this size when securing brackets, flanges, equipment frames, and panel components.

This cap screw is well suited for light commercial and residential trade applications where a standard 1/2-13 coarse-thread fastener is required. It fits into any tapped hole or nut meeting the 1/2-13 UNC specification. The fully threaded shank provides maximum thread engagement across the full 1-1/4-inch length under the head, making it particularly useful in shallow or thin-material fastening situations where partial threading would reduce grip. Minimum order quantity is 25 pieces per order.

Key Features

• 1/2-13 UNC coarse thread for wide compatibility with standard nuts and tapped holes
• 1-1/4-inch length under head, fully threaded for maximum engagement
• Grade 5 steel construction meets strength requirements for general mechanical fastening
• Zinc-plated finish provides basic corrosion resistance for indoor and light-duty use
• Conforms to ASME B18.2.1 dimensional standard
• Inch measurement system, standard hex drive for common wrenches and sockets

Compatibility

Designed for use with any standard 1/2-13 UNC tapped hole or hex nut meeting ASME thread specifications, suitable for general mechanical, structural, and trade-equipment fastening applications.

Installation Notes

Install using a standard 3/4-inch hex wrench or socket drive. Ensure the mating thread or nut is clean and free of debris before installation. Do not overtighten — follow the torque specifications published by the equipment manufacturer or applicable assembly drawings. For outdoor or wet-location applications, evaluate whether a higher-grade corrosion-resistant finish is required beyond standard zinc plating.
