Value Collection HCI40750275N-005BX Hex Head Bolt A490

Product Description

The VALUE COLLECTION HCI40750275N-005BX is a hex head bolt engineered for structural and heavy-duty fastening applications. It features a 3/4-10 UNC thread and a length under head of 2-3/4 inches. The bolt is manufactured from steel to ASTM A490 material grade, a high-strength specification commonly required in structural steel connections. The partially threaded shank allows for controlled load transfer along the unthreaded grip length. The uncoated, bright finish leaves the base material exposed, suitable for applications where coatings are not specified or where field treatment will be applied. Licensed contractors and structural ironworkers are the typical installers of A490-grade fasteners.

This bolt is suited for structural steel assemblies in commercial and industrial construction, including beam-to-column connections and heavy framing where ASTM A490 high-strength bolts are called out in the project specifications. It is also used in heavy equipment fabrication and infrastructure projects requiring verified high-strength fastener grades. The 3/4-10 UNC thread is a common size across a wide range of structural steel connection types. This part is sold individually and may be ordered in single-unit quantities.

Key Features

• ASTM A490 high-strength structural bolt grade for demanding load-bearing applications
• 3/4-10 UNC thread form for broad compatibility with standard structural hardware
• 2-3/4 inch length under head to suit specific grip-length requirements
• Partially threaded shank preserves full shear capacity along the unthreaded grip zone
• Bright uncoated finish meets specifications where surface coatings are not permitted
• Inch measurement system; compatible with standard UNC nuts and washers

Compatibility

Designed as an OEM-style replacement or direct-use structural fastener for applications requiring 3/4-10 UNC hex head bolts meeting ASTM A490 specifications.

Installation Notes

Installation of ASTM A490 structural bolts should be performed by qualified ironworkers or structural contractors in accordance with AISC and RCSC bolt installation specifications. Always power down or de-energize any associated electrical or mechanical systems before accessing structural connection points in live structures. Use calibrated torque wrenches or direct-tension indicators as required by the applicable structural specification. Do not reuse A490 bolts once fully tensioned, as the specification prohibits reuse.
