Timco Dome Head Roofing Bolts with Square Nuts (Silver) - M8 x 40mm (100 Pack Box) (0840RB)
These roofing bolts with square nuts have a large flat mushroom head which evenly distributes the load when clamping thin sheet metal, wood and plastic.
- The fully threaded shank of these roofing bolts makes them incredibly versatile since they can be used to secure thin sheet metal, plastic and wood with a thickness less than the length of the bolts shank.
- A large flat head significantly reduces the chances of damage to sheet materials whilst under stress since the tension is distributed evenly across a wider surface area.
- A zinc plating finish means that these coach screws are only suitable for applications which will remain both clean and dry.
