DIN 464 Knurled Head Screw, Pressure Type, High

The DIN 464 standard covers a high pressure-type knurled head screw of large diameter. The head is fitted with an anti-slip side rib for convenient unscrewing. The screw design includes a cylindrical neck, and the shank is fitted with a full metric thread. The head has no slot, since screws of this type are intended for quick hand tightening and loosening. They are used to create quick-release connections of various parts.

Features and materials

Fasteners made to DIN 464 have a high head that is convenient to unscrew by hand. The part is installed into a hole with metric thread of the matching diameter and is not intended for fixing with nuts. Such a screw is used where a threaded joint needs to be assembled and disassembled repeatedly, making the use of hand tools for unscrewing undesirable.

The following materials are used for manufacturing:

• Steel without a protective coating. Such products do not provide a high tightening force, so no high strength requirements are placed on them.
• Steel with an electroplated zinc coating. It provides long-term corrosion resistance.
• Stainless steels of grades A1-A5. These are used if the connection is constantly exposed to an aggressive environment.
• Brass and aluminium, as well as other non-ferrous metals and their alloys.
• Polymer materials not subject to corrosion.

The choice of material depends on the operating conditions of the connection and the requirements for its durability.

Application possibilities of the fastener

This type of fastener is widely used in furniture manufacturing, and it is also used to create quick-release structures in instrument engineering. The high head of a special shape provides simple and fast unscrewing.
