| This standard specifies requirements for M1,6 to M52 hexagon head screws threaded up to the head, assigned to product grade A, for sizes up to M24 and lengths not exceeding 10d or 150 mm, and to product grade B for sizes greater than M24 or lengths exceeding 10 d or 150 mm. |

• Carton size : The ordinary carton (27*25*14.5CM) , or according to the demand of the customers.
• Packing : plastic bags,Box, carton , then put on pallets, or according to the demand of the customers.
The DIN933 standard is applicable to fully threaded hexagonal screws with thread diameters of M1.6-M52, product grades A and B
Bolt. Class A: d ≤ 24mm and l ≤ 10d or l ≤ 150mm (whichever is smaller). Class B: d>24 mm or l>10d or
1> 150 mm. (By the smaller value). Different product grades have corresponding opposite edges s, diagonal e, thickness k, and length common
The difference values vary.
Surface treatment and thread tolerance: DIN933 hexagonal bolts are generally metric (coarse) and fine, in millimeters
The meter is the unit of measurement. The tolerance of DIN933 coarse thread is 6g, and the coating on the market mainly includes boiling black, electroplating (blue white zinc
Yellow colored zinc, non electrolytic zinc powder covered coating (GEO). The tolerance fit before coating is mainly 6g/6H, and the tolerance zone after galvanizing
The fit can be changed to 6h/6G, but after coating, it is affected by the thickness of the surface coating. Therefore, the thread is tested with a go/no go gauge with the corresponding tolerance
At this time, there may also be situations where it cannot be matched, and only nuts with matching specifications can be installed for testing.
