Coach Screws

SKU: STC06 Categories: ,

Coach Screws, which are otherwise referred to as Lag screws, are heavy duty screws with squared or hexagonal heads and externally threaded shafts.

Used for holding together heavy timber, fixing metal to timber and masonry to concrete, they should not be confused with coach bolts, as the bolts hold a much different shape.

Coach Screws require a pilot hole before they are screwed into place in timber and masonry.

As standard, these screws are manufactured in Stainless Steel which makes them ideal for outdoor use, or coastal areas if the Steel is A4.

There are also a number of finishes that could be useful on coach screws, including bright Zinc Plating, and hot-dipped Galvanising.

Available from Fastenright in both Metric and Imperial threads, in a range of diameters and lengths.

Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and bespoke parts made to drawings. Minimum order quantities apply.
