Metallics SDL14M Screws 14 x 3 Bgl Star D T-17 Deck Scr 18 (1000 pcs)

The Metallics SDL14M is a #14 by 3 inch deck screw with a bugle head and a star (Torx style) drive recess, packed 1000 pieces to the box. The 3 inch length suits fastening nominal 5/4 or 2x decking down into joists, and the bugle head pulls flush into softwood without a countersink.

No pre-drill is needed in dimensional lumber. The SDL14M carries a T-17 point, which is a notched auger-style tip that cuts its own clearance as it drives, so it reduces splitting at board ends and near edges compared with a plain gimlet point. In dense hardwood decking or very close to an end grain edge, a pilot hole is still the safer move.

It takes a star (Torx style) bit, not a Phillips or square. Star recesses hold the bit without camming out, which matters when you are sinking a 3 inch #14 screw at full depth through decking. Make sure you have the matching star bit on hand before the crew starts, since a 1000 piece box will chew through bits on a full deck.

It is a wood deck screw, not a metal fastener. The #14 by 3 inch body with a T-17 wood-cutting point and a bugle head is made for driving into dimensional lumber, decking, framing, and fence rails. For sheet metal, strut, or electrical enclosures you want a self-drilling sheet metal or Tek type screw instead.

Each box of SDL14M holds 1000 screws. At the common two screws per board per joist, that covers a fair amount of deck surface in a single carton, which is why the bulk pack suits contractors and maintenance crews standardizing on one fastener rather than buying small jars per job. Order by the box when you want every deck on a property fastened with the same head and drive.
