Description du produit

DIN 931 zinc plated carbon steel hex head bolts are partially threaded fasteners designed for strong and reliable mechanical connections. The product features a standard hexagonal head, a smooth shank section, and a threaded end, making it suitable for applications where alignment, clamping force, and structural stability are required.

Made from carbon steel and available in strength grades 8.8 and 12.9, these bolts provide high fastening performance for construction hardware, machinery assembly, steel structures, equipment installation, and general industrial use. The zinc plated surface provides a clean silver appearance and helps improve corrosion resistance for normal indoor and dry-environment applications.

The hex head design allows easy installation with standard wrenches or sockets. The partial thread structure helps reduce thread contact along the full bolt length, making the bolt suitable for assemblies requiring shear strength through the unthreaded shank area.

FAQ

Q1: What is the difference between DIN 931 and DIN 933 bolts?

R : DIN 931 bolts are partially threaded, while DIN 933 bolts are fully threaded. The product shown is a partial thread hex head bolt, so DIN 931 is more suitable.

Q2: What material is this bolt made of?

R : This bolt is made of carbon steel.

Q3: What surface treatment does this bolt have?

R : The bolt has a zinc plated surface treatment with a silver / blue-white zinc appearance.

Q4: What strength grades are available?

R : Grade 8.8 and Grade 12.9 are available.

Q5: Where can this bolt be used?

R : It can be used in construction hardware, machinery assembly, steel structures, equipment installation, and general industrial fastening.

Q6: Can you supply different sizes?

R : Yes. Common metric sizes include M6, M10, M14, and other sizes can be supplied according to order requirements.
