Professional Applications & Engineering Value
This Grade 5 zinc-plated steel carriage bolt delivers critical engineering solutions for industrial assembly challenges. The knurled neck beneath the wide rounded head provides exceptional anti-rotation performance, eliminating the need for additional locking mechanisms in wood-to-metal and structural applications. The UNC coarse thread configuration with Class 2A fit ensures rapid installation in soft materials while maintaining superior pull-out resistance. With 120,000 psi tensile strength and Rockwell C25 hardness, this fastener maintains structural integrity in heavy machinery, construction frameworks, and transportation equipment where vibration resistance and long-term reliability are paramount. The zinc-plated steel construction offers balanced corrosion protection for both indoor and outdoor industrial environments.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit tolerance and UNC coarse thread specifications. This carriage bolt complies with SAE J429 mechanical requirements for Grade 5 fasteners and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance standards. The inch system measurements ensure compatibility with North American industrial specifications and replacement part requirements.
