CARRIAGE BOLT
CARRIAGE BOLT DIN-603
📌 Overview
The Stainless Steel Carriage Bolt DIN 603 is a round head bolt with a square neck beneath the head. The square neck locks into the material, preventing rotation when tightening the nut – making it ideal for wood-to-metal and wood-to-wood fastening.
Manufactured from SS 304 (A2) and SS 316 (A4), these bolts combine strength, safety, and excellent corrosion resistance, making them widely used in construction, furniture, automotive, marine, and public infrastructure.
