Value Collection HCI203103500FT-050BX Hex Cap Screw

Product Description

The VALUE COLLECTION HCI203103500FT-050BX is a fully threaded hex head cap screw designed for general-purpose fastening in mechanical assemblies, structural connections, and equipment fabrication. It features a 5/16-18 UNC thread size with a 3.5-inch length under head, providing substantial grip length for through-bolted joints and deep-engagement applications. Manufactured from Grade 2 steel with a zinc plating finish, this fastener balances corrosion resistance with cost-effective performance in light to moderate load applications. It is installed using standard hex tooling and suits a wide range of trade and industrial maintenance tasks.

This fastener is suited for use in residential and light commercial construction, HVAC equipment mounting, plumbing fixture support, electrical enclosure assembly, and general equipment maintenance. The fully threaded configuration along the entire shank makes it well matched to thin-material joints and applications requiring full thread engagement from head to tip. Tradespeople across plumbing, HVAC, electrical, and general mechanical service regularly stock this size for field repairs and new installations. Minimum order quantity is 50 pieces.

Key Features

• 5/16-18 UNC thread for compatibility with standard inch-system fastener hardware
• 3.5-inch length under head provides extended grip for deep or through-bolted assemblies
• Fully threaded shank maximizes thread engagement across the full fastener length
• Grade 2 steel construction meets general-purpose structural fastening requirements
• Zinc-plated finish provides baseline corrosion resistance for indoor and light outdoor use

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 5/16-18 UNC tapped hole or nut in general mechanical, HVAC, plumbing, and electrical installation applications.

Installation Notes

Install using a standard hex wrench, socket, or combination wrench sized for a 5/16-inch hex head cap screw. Ensure mating threads are clean and free of debris before assembly. Do not overtighten into soft materials or thin sheet stock, as Grade 2 steel has lower proof load ratings than Grade 5 or Grade 8 fasteners. Follow applicable mechanical codes and equipment manufacturer torque guidance when installing in load-bearing or safety-critical joints.
