The Grade 12.9 Hex Head Bolts specification exceeds the standard 10.9 grade bolts in terms of its tensile strength characteristics by approx. 25% for that extra margin of safety. The minimum ultimate tensile strength of the Grade 12.9 Metric Hex Head Bolts is about 1242 Mpa or 180,000 PSI, making them the highest grade of bolts produced.In fact, the Grade 12.9 Nuts is known for their high tensile strength.

The dimensions of the Grade 12.9 Threaded Bar standard conforms to both the ISO 4014  specification as well as the 4017 specification. The only exception between the latter and later specifications being the increased head height for better wrenching ability in the Grade 12.9 Studs. The head of the  can be built either in the hex form or in the Torx form.

An additional feature of the Grade 12.9 Metric Bolts is its special or improved fatigue-resistant MJ (UNJ) thread form, which meets the ANSI dimensions standard specifications. Besides, the 12.9 Grade Allen Bolt is available in the market with either in zinc or chrome plating with the diameter size of the Class 12.9 Hex Bolt ranging from M5 to M160.

Grade 12.9 Hex Bolts are tightened with a torque wrench. This torque wrench tightens the bolt up to 90 percent of its proof load. Because of the hardened surfaces of the Grade 12.9 Material, lock washers are ineffective as  they can't bite into the metal. Manifold Pipe Solution Inc. is one of the leading distributors and Grade 12.9 Bolts Suppliers.
