M12 Bolt

Frequently Asked Questions

Q: What are the dimensions of the ML M12-1.75X55-BOLT?
A: The ML M12-1.75X55-BOLT is an M12 x 1.75 x 55mm bolt. M12 is the 12mm nominal diameter, 1.75 is the metric pitch, and 55mm is the grip length (shank length beneath the head). Always verify length and thread pitch against your original equipment specifications before ordering.

Q: What equipment and assemblies use M12 x 1.75 bolts like the ML M12-1.75X55-BOLT?
A: M12 x 1.75 bolts are used in hydraulic systems, pump assemblies, cylinder connections, and structural fastening on Crown, Toyota, Raymond, Yale, Hyster, and Jungheinrich material handling equipment. Common applications include mast connections, steering components, and axle assemblies. Refer to your equipment manual to confirm compatibility and bolt head style.

Q: What is the tensile strength and material of the ML M12-1.75X55-BOLT?
A: Industrial-grade M12 bolts are typically manufactured from carbon steel or alloy steel with a tensile strength of 400 MPa (Grade 8.8 or equivalent). The exact grade depends on original equipment specification. Bolts may be plain, zinc-plated, or galvanized for corrosion resistance. Contact us with your equipment model for specific material and coating details.

Q: Can the ML M12-1.75X55-BOLT be reused after removal?
A: Yes, but inspect it for damage, corrosion, or thread stripping before reuse. If the bolt shows signs of deformation, rust, or stripped threads, replacement is recommended. High-stress fasteners in hydraulic or steering systems should be replaced during major overhauls to maintain equipment safety and reliability.

Q: What is the correct lock nut for the ML M12-1.75X55-BOLT?
A: Use the ML M12-1.75-NUT (M12 x 1.75 lock nut) with the ML M12-1.75X55-BOLT. Both share the same metric thread pitch and diameter, ensuring proper fit and vibration resistance in high-movement assemblies like masts and hydraulic connections.
