DIN 604 Furniture Bolt with Countersunk Head and Lug

The furniture bolt to DIN 604 has a distinctive design. It is a solid metal cylinder, one end of which (approximately one third of the length) carries metric thread. At the opposite end is a head with a flat top, and on its underside there is a rib or lug. This element provides more reliable fixation of the fastener in the material being joined, preventing it from rotating.

Technical specifications

The Russian equivalent of DIN 604 is GOST 7785-81. The furniture bolt with countersunk head and lug meets its requirements. Key characteristics:

• raw material – carbon or stainless steel, property class 3.6 or 4.6;
• zinc-plated (electrogalvanized) coating when carbon steel is used;
• fastener length – from 20 to 160 mm;
• partial thread on the shank within M6-M24.

Bolts made of chromium-nickel or oxidized steel have high strength properties, are reliable and durable.

Installation technology

The DIN 604 furniture bolt with countersunk head and lug is used when assembling furniture items:

• the joint points of the parts to be connected are marked out;
• a hole of the specified diameter is drilled at the marked points;
• the bolt is installed, and a nut is screwed onto its threaded end.

To increase the bearing area and improve the reliability of the connection, a flat washer is placed under the nut. After the fastener is tightened, its head is recessed into the surface of the base; a decorative plug is used to cover the hole.
