DIN 603 A2 Stainless Steel Carriage Bolts with Square Neck M5–M8, 16–100 mm
DIN 603 carriage bolts, also referred to as TTQST 603 bolts, are manufactured from A2 stainless steel and designed for various mechanical and structural fastening applications. Their rounded head provides a smooth external surface, while the square neck beneath the head helps prevent bolt rotation when properly seated in the mounting material.
The A2 stainless steel construction provides corrosion resistance for indoor, outdoor and moisture-exposed applications. These bolts are suitable for general fastening and assembly work where a rounded head and square-neck bolt design are required.
The range includes six dimensional configurations with nominal diameters of 5, 6 and 8 mm and lengths from 16 to 100 mm. Each version is identified by its individual FNI product number.
