Strong-Drive® XM MEDIUM-HEAD METAL Screw (Collated)

Strong-Drive® XM MEDIUM-HEAD METAL Screw

On This Page

Strong-Drive metal screws are load-tested and code-listed, allowing you to get the maximum load values for installation. Comparison testing shows Strong-Drive XM Medium-Head Metal screws are stronger than many alternative fastener types in 33 ksi and 50 ksi steel decking.

Key Features

  • 5/16" hex drive
  • 1/2"-dia. hex washer head is ideal for narrow-channel steel decking
  • Available only in 1 1/4" length with #5 drill point
  • Available in Quik Guard® coating
  • Also available in bulk for hand-drive installation
  • US Patent 9,518,599

Applications

  • Steel decking to structural members involving wide or narrow valley; nestable or interlocking steel decking

Warning

  • Industry studies show that hardened fasteners can experience performance problems in wet or corrosive environments. Accordingly, use this product in dry, interior and noncorrosive environments only.

Load Tables

Screw Shear and Tension Strengths

  1. Pss and Pts are nominal shear strength and nominal tension strength for the screw itself, respectively, and are the average (ultimate) value of all tests determined by independent laboratory testing.
  2. The ASD and LRFD loads for tension are calculated using a safety factor Ω of 3.0 and the resistance factor Φ of 0.5, respectively.
  3. For tension connection: the smallest of the screw tension strength, pull-over strength and pull-out strength shall be used for design.

Structural Screw Pull-Over Strength with Steel Minimum Yield Strength Fy = 33 ksi

  1. Values are based on steel members with a minimum yield strength of Fy = 33 ksi and tensile strength of Fu = 45 ksi.
  2. The values for 16 ga., 18 ga., 20 ga. and 22 ga. are based on tests per AISI Standard Test Method S905.
  3. The safety factor Ω and resistance factor Φ used to determine the ASD and LRFD strengths are based on AISI S100.
  4. The values for 16 ga., 18 ga., 20 ga. and 22 ga. are based on the calculations per AISI S100.
  5. For tension connection: the smallest of the screw tension strength, pull-over strength and pull-out strength shall be used for design.

Structural Screw Pull-Out Strength

  1. Values are based on calculations per AISI S100.
  2. The tabulated ASD and LRFD loads are based upon a safety factor Ω of 3.0 and the resistance factor Φ of 0.5.
  3. For tension connection: the smallest of the screw tension strength, pull-over strength and pull-out strength shall be used for design.
