M16 x 50mm Coach Bolt / Carriage Bolt in Zinc Plated 8.8 - DIN 603

Generally used in timber to timber and timber to metal construction, these bolts incorporate a square neck to grip the hole in the timber when fitting, and therefore negates the need for any drive recess to be included on top of the head. Supplied to DIN 603. Please note that thread lengths stated are a minimum; In some cases a full thread will be supplied where a partial threaded shank is indicated in the specification. Nuts are supplied seperately, unlike the mild steel versions available elsewhere on the site.
