Torx Alloy Steel Socket Head Stepped Screws

A Torx-Plus drive has more points of contact than a hex drive, allowing you to tighten these screws with less slippage or damage to the recess. With a tensile strength of 180, 000 psi, these alloy steel screws are stronger than Grade 8 steel screws. Their black-oxide finish provides mild corrosion resistance in dry environments. They can be used with both Torx-Plus and standard Torx tools (see Torx bits and Torx keys and drivers). Screws meet ASTM A574 specifications and testing requirements for material quality. Length is measured from under the head. Serrations under the head act as a brake to prevent overtightening and damaging threads. The flange reduces the risk of crushing thin metal. They save you time and effort by drilling their own holes and fastening in a single operation. A hex head provides a larger gripping area for installation with a wrench or socket driver. Length is measured from under the flange. Head height includes the flange. External Hex/Torx drive screws give you the choice to install with a wrench or a Torx driver. Zinc-plated steel screws resist corrosion in wet environments. Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.
