DIN 1445 Oval Head Bolt with Pin

DIN 1445 covers a special fastener type — a bolt with a flattened oval head and a threaded pin. The fastener is used to create a strong threaded connection between structural and equipment components. It consists of a metal shank without thread, a head, and an additional threaded pin of reduced diameter. The product is installed into a hole of matching diameter and secured with a nut. The fastener is produced in a wide range of sizes and is suitable for use in mechanical engineering, instrument making and other fields.

Features

The material used is carbon steel, which is coated by hot-dip or electroplated galvanizing for corrosion protection. Stainless steel A2 and A4, brass, and other non-ferrous alloys are also used.

Product specifications:

• Nominal thread diameter — from M6 to M24.
• Main shank diameter — from 8 to 30 mm.
• Head diameter — from 14 to 44 mm.

The product provides reliable fastening of components. The zinc coating extends service life and protects against corrosion.
