Sheradised Square Twist Nails are invalueable when working with timber construction. This pack of 500 joist hanger nails from BPC are designed to secure joist hangers in roofing ceiling flooring and decking work. The nail is 30 mm in length with a twisted shank to ease entry and give a better hold. The small round head provides a subtle finish. A joist hanger holds timber joints in place by preventing movement. 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. This gives them an extra level of durability that makes them able to withstand a range of environmental conditions. They're just as suitable for outdoor constructions as they are for indoor ones.
