# 8 x 1/2" wafer truss head self drilling screws 5000
* # 8 x 1/2" Self drilling wafer head screws
* Comes with (4) # 2 lox bits ( Google lox bits)
* Wafer head, drill point framing screws for heavy gauge metal applications. Wafer head provides a greater bearing surface than Pan or Hex Drillers, with a low-profile head exposure. For 14 - 20 gauge steel.
Driving torque is distributed to 8 points of contact. 4 points of contact offer better torque than a Phillips recess as the force vectors are perpendicular to a line through the center. Phillips are offset. The other four points of contact provide the equivalent torque of a typical square recess. Add them together and you get MAXIMUM TORQUE! Driver bits last much longer. Stick fit lasts longer eliminating the need to use a magnetic bit holder. Productivity is increased. Less wobble. Fewer flop overs. Much less operator fatigue. The best of all worlds!
In a recent independent test, LOX screws demonstrated more than triple the torque capacity of square. Applying increasing torque to the recess, the square drive cammed out with 37.79 Kgf-cm, which is well before the screw could be fully driven and seated. In every comparable test the LOX recess screw seated completely, with an average force of 82.11 Kgf-cm. In other tests, the LOX screw tolerated the maximum 100 Kgf-cm of force delivered by the test equipment and still did not cam out. In other words, the LOX exceeded the ability of the testing equipment to apply force. That's MAXIMUM TORQUE
