Pack of 5 Hexagon head coach screws, steel, bright zinc plated, size M12 x 100mm. Hexagon head size 19mm measured across the flats, so you need a 19mm spanner or socket. Thread diameter 12mm. The size refers to the diameter of the screw thread and the length of the screw part from the point to under the flat head. The overall length will be 8mm longer than the stated size because it includes the thickness of the hexagon head.
These are ideal for use for joining timber together, or together with 16mm nylon plugs for making a strong fixing into less hard types of masonry.
Big discounts if you buy more than one pack due to the saving on postage!
