Structural connectors specifically designed to secure joist hangers in roofing, decking, flooring and ceiling work. Each nail measures 30 mm in length and has a twisted shank for easier entry and a better hold. The small round head helps to create a subtle finish. Joist hangers hold timber joints in place by preventing them from twisting and moving. Insert these specialised nails via the holes in the hanger to provide extra stability. They're sheradised to give a zinc coating, making them corrosion-resistant, which adds durability and allows them to withstand a range of environmental conditions, making them suitable for both outdoor and indoor constructions. Meets EN14592:2008 standards. Approximately 500 nails per 1.25kg bag.
