What is the difference between a bolt and a setscrew?
In UK trade usage a bolt (DIN 931) has a plain shank below the head and a setscrew (DIN 933) is threaded along its full length. Use the bolt where the joint plane should bear on the plain shank, the setscrew where thread is needed right up to the head.
Which square neck bolt do I need?
Three patterns share the anti-rotation square neck: the coach bolt DIN 603 with a smooth domed head, the countersunk DIN 608 that pulls flush with the surface, and BS 7419 holding-down bolts for securing steelwork to foundations. Choose by the job: smooth finish, flush finish, or foundation fixing.
Which eye bolt is for lifting?
Only the collared lifting eyebolt DIN 580 is a lifting point - the swing bolt DIN 444 is a quick-release clamping bolt and is not rated for lifting. Certification for lifting eyebolts is available on request.
