DIN912
HINA
HINA2024120501
DIN912 is a German industrial standard that specifies the basic specifications of hexagon socket bolts. Knurled DIN912 hexagon socket head bolts are based on standard hexagon socket head bolts, with a knurled process added to the head. Knurling is a process of forming patterns on metal surfaces, usually by rolling tools to produce regular patterns on the outer circumferential surface of the bolt head.
Head knurling: Its most distinctive appearance feature is the knurling on the head. Knurling patterns come in various forms, the most common ones being straight knurling and mesh knurling. Straight knurling is a series of parallel straight lines formed on the surface of a cylinder, while textured knurling is a cross-reticular pattern. These patterns not only increase the aesthetics of the bolt head, but also have an anti-slip function. The knurling provides better friction when using a wrench or other tool to tighten or loosen a bolt, making it easier to operate, especially if you have oily hands or are wearing gloves.
The internal hexagonal structure is still retained: there is still a standard internal hexagonal groove in the center of the head, which is used to insert an internal hexagonal wrench for tightening operations. It is the same size as the internal hexagonal part of ordinary DIN912 internal hexagonal bolts, ensuring the versatility of the tool.
Rod part and thread: The rod part is cylindrical and has threads on the surface. The specifications of the thread meet the requirements of DIN912 standard and can closely match the corresponding nut or parts with internal threads to achieve the connection function.
Occasions requiring frequent disassembly: Since the knurling on the head provides better operability, it is widely used in equipment that requires frequent disassembly and installation of bolts. For example, in the tool changing devices of some mechanical processing equipment, the use of knurled hexagon socket bolts can facilitate the operator to quickly remove and install the tool fixing bolts, improving work efficiency.
Environments that require anti-slip: In some environments that may be affected by oil stains, water stains or where operators need to wear gloves, the anti-slip effect of knurling is particularly important. For example, during the assembly and maintenance of automobile engines, the hexagonal knurled bolts on the engine components allow maintenance personnel to operate easily even if their hands are oily.
Products with special requirements for appearance: knurling can increase the aesthetics of the product. For some equipment or products that have requirements for appearance design, such as high-end precision instruments, partially customized mechanical products, etc., hexagon socket bolts with knurling can be used as A fastener that is both decorative and practical.
advantage:
1. Excellent anti-slip: The knurling on the head increases friction and prevents slipping. It is still convenient to operate when it is stained with oil or wearing gloves, such as in car maintenance scenarios.
2. Beautiful and exquisite: regular patterns improve appearance and texture, suitable for high-end instruments, customized machinery and furniture, etc., and are both decorative and practical.
3. Torque improvement: Increase the contact area and friction, stabilize the torque transmission, and make the connection tighter. It is suitable for heavy loads or vibration environments.
4. Diversified materials: Carbon steel, stainless steel, alloy steel and other materials are available, which can meet different environmental and performance requirements and are widely used.

How many types of Allen bolts are there?
There are several types of Allen bolts:Standard Allen Bolt、Button Head Allen Bolt、Flat Head Allen Bolt、Socket Cap Bolt、Set Screw (Grub Screw).
What is another name for Allen screws?
Another name for Allen screws is socket screws or hex socket screws.
What is the difference between a socket screw and a hex bolt?
A socket screw has a hexagonal socket for an Allen key, while a hex bolt has a hexagonal head for a wrench or socket.
