January 17, 2022 — BRYAN, Ohio — Altenloh, Brinck & Co. US, Inc (ABC US) received a new technical evaluation report (DrJ Engineering’s TER 2010-02) for SPAX® Construction Screw Properties.

“Technical reports and outside certifications are critical for a number of reasons,” said Eric Ashack, SPAX® Product Manager. “First, we know these reports are important to our customers – they provide guidance and peace of mind for dealers, contractors and builders. These third-party certifications are also key because they validate the engineering and comprehensive testing we do in-house.”

For this DrJ Engineering technical report, SPAX® Construction Screws were tested and evaluated to determine their structural resistance properties, which are used to develop reference design values for allowable stress design. The following properties were evaluated: bending yield, tensile strength, shear strength head pull-through, withdrawal strength, lateral resistance and corrosion resistance.

SPAX® construction screw types covered in this TER include:

Carbon Steel Fastener Types

  • #6, #8, #10, #14 Unidrive Flat Head – zinc and yellow zinc coating
