Value Collection IAMB1750450FP Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION IAMB1750450FP is a heavy-duty hex head cap screw designed for high-strength bolted assemblies in industrial, structural, and mechanical applications. Manufactured from Grade 8 steel with no additional coating, this fastener measures 1-3/4 - 12 UNC thread size and 4-1/2 inches in length under head. The partial threading design concentrates clamping force in the joint, making it well suited for through-bolt applications where shank grip is required. At 4.5 pounds, this is a substantial fastener appropriate for demanding load-bearing connections. Tradespeople and maintenance professionals working in fabrication, construction, and heavy equipment service will find this screw sized for large-format assemblies.

This cap screw is used in applications requiring a high-strength inch-series fastener with a coarse UNC thread pitch. Typical installation scenarios include structural steel connections, heavy machinery frames, industrial equipment mounting, and large-bracket assemblies where Grade 8 tensile and proof load ratings are specified by design or code. The uncoated finish is appropriate for environments where a secondary coating, paint, or galvanic protection will be applied after assembly, or where bare steel contact surfaces are acceptable per the application specification.

Key Features

• Grade 8 steel construction for high tensile strength and hardness in demanding bolted joints
• 1-3/4 - 12 UNC thread size in the inch measurement system for large-diameter coarse-thread applications
• 4-1/2 inches length under head provides substantial grip range for thick structural members
• Partially threaded shank maintains shear strength and concentrates clamping in the joint
• Uncoated finish compatible with field-applied coatings or bare-steel assembly requirements
• Hex head drive accepts standard hex socket and open-end wrenches common in trade and industrial settings

Compatibility

Designed as an OEM-style replacement or direct-use fastener for large-format structural and mechanical assemblies requiring a 1-3/4 - 12 UNC Grade 8 hex head cap screw with partial threading.

Installation Notes

Installation should be performed by a qualified tradesperson or maintenance technician familiar with high-strength fastener torque requirements per the applicable structural or mechanical standard. De-energize and lock out all power sources before accessing any equipment being serviced. Use calibrated torque tooling appropriate for large-diameter Grade 8 fasteners and follow the relevant AISC, ASME, or equipment manufacturer torquing procedure. Do not substitute a lower-grade fastener in any joint specified for Grade 8 hardware.
