About this bolt
This is a bolt in Carbon Steel, at strength class Grade 4.8, supplied zinc plated, with an M6 thread. Every dimension is stated against the standard named above; where a tolerance class matters to your design, ask us and we will confirm it in writing before you order.
A bolt passes through the parts it joins and is closed with a nut, so the joint is held by the clamp load the tightened bolt develops rather than by the shank itself. Bolts of this type are used on structural steelwork, machine frames, brackets, flanges and pipework — anywhere the joint has to come apart again for maintenance.
M6 is a metric thread with an 6 mm nominal diameter and a coarse pitch of 1 mm (ISO 261). A standard hex head takes a 10 mm spanner across the flats.
Carbon steel is the workhorse material for structural fastening. Grade 8.8 and above must be coated (zinc, black oxide or Dacromet) or it will rust outdoors.
There is no minimum order and no free-shipping threshold: buy one piece or a full container. Your order total is confirmed in the cart, before payment.
