Product Overview: Specifications & Features

DIN933 Hex Bolt adheres to the DIN 933 standard for hexagon head bolts, ensuring compatibility with global industrial assemblies.
Short Description: Length is measured from the point at which the head sits flat with the surface, to the tip of the threads. Hex, pan, truss, button, socket cap, and round head screws are measured from right under the head to the end of the threads. Flat head screws are measured from the top of the head to the tip of the threads.

Professional FAQ: DIN933 Hex Bolt

Q1: What materials are DIN933 Hex Bolts made of?

A: din933 hex bolt is manufactured from mild steel for general purposes and from stainless steel grades (A2 – 304, A4 – 316) for corrosion resistance, with options for alloy steel in high-strength applications.

Q2: How is the thread specified?

A: DIN 933 bolts employ a full metric thread, with sizes such as din 933 m10 indicating a 10mm nominal diameter.

Q3: What is the typical property class?

A: Property classes denote tensile/yield strength: 4.8 (standard), 8.8 (high strength), 10.9 and 12.9 (very high strength) conform to ISO 898-1 standards (Bossard).

Q4: What are the surface finishing options?

A: Zinc plated (for general anti-corrosion), hot-dip galvanized (HDG) for heavy-duty outdoor, black oxide and plain finishes protect DIN933 hex bolt in different environments.

Q5: How do I select the correct DIN933 size?

A: Choose based on thread diameter (e.g., din 933 m10), length, and property class according to the load and installation requirements.

Q6: What are key installation standards?

A: Installation should conform to DIN/ISO standards, using calibrated torque tools and matching nuts/washers. Ensure joint surfaces are clean and free of lubricants for predictable performance.

Q7: Are DIN933 bolts suitable for outdoor use?

A: Yes, particularly bolts produced from din 933 a2 stainless steel or with HDG/zinc plating, making them ideal for outdoor, marine, and aggressive environments (Fastener Engineering).
