About Tapping Screws

For a finished appearance that reduces the chance of snags on other material, these screws fit snugly in countersunk holes and have a domed head. Made from 18-8 stainless steel, they resist corrosion in damp and washdown environments, as well as from chemicals. Also known as tapping screws, they cut their own threads as you tighten them—allowing you to thread a pilot hole and fasten your metal in a single step. All meet ISO 7051 (formerly DIN 7983), an international standard for fastener dimensions.

Stainless Steel Thread-Forming Screws for Thin Plastic

18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. They have a round shank and more sharply angled threads than other thread-forming screws, so they require less driving torque and reduce the risk of cracking thin plastic. A Torx drive allows you to apply extra force with less slippage or damage to the recess.

Pan head screws are also known as Delta PT® screws. Length is measured from under the head.

Round head screws have a flange under the head that distributes holding pressure and reduces the risk of crushing thin plastic. They’re comparable to EJOT PT screws. Length is measured from under the flange.

Stainless Steel Torx Rounded Head Thread-Forming Screws for Plastic

Torx-Plus Drive

These 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. A Torx or Torx Plus drive provides more points of contact than a Phillips drive, allowing you to apply extra force with less slippage or damage to the recess. Comparable to Plastite screws, these screws have a triangular shank that presses tightly against formable plastic such as polypropylene to resist loosening. Length is measured from under the head.
