Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these M12 carriage bolts solve critical fastening challenges where vibration resistance and structural integrity are paramount. The zinc yellow-chromate plated steel construction provides exceptional corrosion protection in outdoor equipment, agricultural machinery, and construction frameworks. The square neck design prevents rotation during torque application, eliminating the need for secondary locking mechanisms in wood-to-metal and structural steel connections. With fully threaded coarse pitch threading and Class 8.8 strength rating, these metric fasteners deliver maximum clamping force in transportation equipment, trailer assemblies, and industrial machinery where 110,000 PSI tensile strength ensures long-term reliability under dynamic loads.
Specification Summary & Compliance
This carriage bolt features precision Metric M12 x 1.75mm coarse threading with Class 6g thread fit tolerance ensuring consistent engagement. Manufacturing complies with ISO 8678 specifications for dimensional accuracy and performance standards. The 50mm length with 4mm square neck (12.7mm width) provides secure anti-rotation characteristics. Material composition and zinc yellow-chromate plating meet international environmental regulations including RoHS and REACH compliance for global industrial use.
