Value Collection HCI50750375G Hex Head Cap Screw 3/4-10

Product Description

The VALUE COLLECTION HCI50750375G is a 3/4-10 UNC partially threaded hex head cap screw measuring 3-3/4 inches under the head. Manufactured from Grade 5 steel with a hot-dipped galvanized finish, this fastener is engineered for structural and mechanical assemblies where corrosion resistance and tensile strength are both required. The hot-dipped galvanized coating provides a thicker, more durable zinc layer compared to electroplated alternatives, making it well suited for outdoor, wet, or high-humidity environments. Licensed trades and industrial maintenance crews rely on Grade 5 fasteners as the standard for general structural bolting applications.

This hex head cap screw is used in a wide range of trade and industrial applications including HVAC equipment mounting, structural steel connections, mechanical equipment bases, outdoor electrical enclosures, and plumbing infrastructure supports. The partial threading allows for a smooth shank section that resists shear loading at the joint interface, which is advantageous in wood-to-metal or metal-to-metal assemblies where thread engagement is controlled by nut or tapped hole depth. Suitable for both new installation and maintenance replacement work across residential and commercial job sites.

Key Features

• Grade 5 steel construction meets SAE tensile and proof load requirements for medium-strength structural bolting
• Hot-dipped galvanized finish delivers heavy zinc coating for enhanced corrosion resistance in outdoor and wet environments
• 3/4-10 UNC thread form provides broad compatibility with standard inch-system nuts, washers, and tapped holes
• Partially threaded shank resists shear forces and provides a bearing surface at the joint
• 3-3/4 inch length under head accommodates a range of material stack thicknesses

Compatibility

Designed for use with standard 3/4-10 UNC nuts, flat washers, and lock washers in inch-system assemblies. Compatible with tapped holes and hardware conforming to UNC thread standards across HVAC, plumbing, electrical, and general mechanical applications.

Installation Notes

Installation is performed using a standard 1-1/8 inch hex wrench or impact socket. Power down or de-energize any equipment before fastener removal or installation in electrified assemblies. Follow applicable code requirements and equipment manufacturer torque guidance for the joint material and application. Do not mix galvanized fasteners with incompatible dissimilar metals in corrosive environments without appropriate isolation measures.
