18-8 Stainless Steel Button Head Torx Screws


Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. All are passivated for added protection against oxidation and corrosion. Torx and Torx-Plus drives have more points of contact than other drives, allowing you to tighten the screw without damaging the recess. For Torx tools, see Torx and Torx-Plus bits, keys, and drivers. Torx-Plus screws can be used with both Torx-Plus and Torx tools. Length is measured from under the head.

Steel Pan Head Torx Screws


These screws have a Torx or Torx-Plus drive for more points of contact than other drives, allowing you to tighten the screw without damaging the recess. For Torx tools, see Torx and Torx-Plus bits, keys, and drivers. Torx-Plus screws can be used with both Torx-Plus and Torx tools. Length is measured from under the head.
Black corrosion-resistant-coated steel screws resist chemicals and withstand 96 hours of salt spray.

Steel Thread-Forming Screws for Thin Plastic

These steel screws are zinc plated to resist corrosion in wet environments. 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. Length is measured from under the head.
Style A screws are also known as Delta PT® screws.

Torx Bits



Strong and durable, these multipurpose bits are often used with power tools to install sheet metal screws.
Hex shank bits (also known as insert bits) are used in hand drivers or with a bit adapter in power tools.
Hex shank bits for power tools have a groove in the shank and fit directly into power tools without an adapter. They offer more reach for recessed holes and less wobble compared to a hex shank bit used with an adapter.

Static-Control Precise-Control Screwdrivers


Also known as ESD-safe screwdrivers, the handle drains static away from your application, preventing buildup from electrostatic discharge (ESD) that can damage sensitive equipment. Press the rotating end cap on the handle with your palm to apply constant pressure while turning the body of the screwdriver with your fingertips.
Static-dissipative drivers divert static electricity faster than antistatic drivers. They meet IEC 61340-5-1 requirements for protecting electronic devices from electrostatic discharge.
Warning: Because the handle conducts electricity, screwdrivers must not come in contact with sources of electrical power.
