WebbNo-strip star drive resists stripping and cam-out with 33% less drive force increasing battery life. Countersinking Blades Self-countersinking blades under the head of the screw cut a perfect finished hole by transporting wood fibers out, sealing the surface with 75% less splitting than standard screws No Splitting Twist Shank Webb10 nov. 2024 · Table 2 shows the specifications of the screws. The diameter and length for first type of screw (Ø6.5 × 65 mm) were 6.5 mm and 65 mm, and those for the second type of screw (Ø8.0 × 100 mm) were 8.0 mm and 100 mm. Table 2 Specifications of screws [ 37] Full size table Withdrawal resistance test WebbThis data article describes the datasets obtained during the development phase of “Post-installed Screw Pullout (PSP) test”, a new in-situ test for concrete strength assessment. The datasets presented focus on the results obtained in mortar samples. The presented PSP test method is based on a post-installed screw being pulled from the parent material. fantech fr250
