DIN 466 Knurled Nut (Thumb Nut), High, Round

DIN 466 is a knurled round thumb nut. The fastener has a cylindrical shape, with knurling on the end face and ribbing. This design allows the nut to be tightened by hand, without using tools.

This makes it convenient for use in joints that require frequent loosening and tightening. Nuts of this type are in demand in furniture manufacturing, instrument making and other production industries.

Materials

Knurled thumb nuts are made from various materials. Carbon steel with property class 5 is used, and the metal can be supplemented with a zinc coating for corrosion protection. The nuts are also made from stainless steel grades A1, A2 and A4 — strong acid-resistant alloys that withstand prolonged contact with aggressive media.

Brass and aluminium alloys are also used for production — non-ferrous metals are not subject to corrosion and are not affected by contact with moisture or chemically active substances. Products made from non-ferrous metals feature a long service life and reliability. For demanding conditions, plastic nuts are used.

Technical specifications

Round thumb nuts have the following set of technical characteristics:

• The thread diameter of the nut’s central hole ranges from M1 to M10, suitable for use with various bolts, screws and other types of fasteners.
• The height of the product’s knurled head ranges from 1.5 to 8 mm.
• The maximum diameter of the product ranges from 5.5 to 36 mm.
• The diameter of the product’s lower part can range from 2.8 to 20 mm.

The wide dimensional range allows selecting a steel nut with the required parameters. Analogues of this fastener are manufactured to the DIN 467 standard, the difference being a reduced product height.

Conditions of use

The nuts are designed for hand-tightening. For slip protection and ease of tightening, the end face is fitted with ribbing. This type of fastener is widely used in furniture assembly and the manufacture of various instruments, and is suitable for installation where manual adjustment of length and other parameters is required. The fastener is also in demand in other areas of mechanical engineering, as its non-standard shape has provided it with broad application possibilities.

FLOK supplies special-purpose fasteners: a wide range of sizes is available in the product range. The products comply with established standards. Supply is carried out wholesale, in batches of any size.
