SPAX PowerLags offer the largest selection of code-recognized structural wood-to-wood fasteners in the industry. Featuring SPAX patented thread technology, they require no pre-drilling, and drive faster and easier than conventional lags and other structural screws
Washer head: The washer-like head of the screw enlarges the contact surface on the workpiece, thus guaranteeing considerably higher tightening torques compared to a countersunk screw. The SPAX washer head enables better tightening of joints between pieces of wood. The washer head is available for SPAX screws with an outer thread diameter of 5.0 mm.
The Hex Head can also be turned while the bolt is being inserted into a tapped hole to match the threads.
They are the industry standard for forged head fasteners and come in different Grades, coatings and materials. Check local building requirement for code on fasteners before building.
SPAX® 4CUT® point: The 4CUT® point enables fastening without pre-drilling (depending on the wood). This is achieved through its special screw tip. The arrow shape pushes through the fibres of the wood, ensuring a fast grip. This effectively prevents the material from splitting and reduces the insertion moment. For hard woods, we recommend pre-drilling even when using SPAX with 4CUT.
Deep Thread: Characterized by a reduced diameter shank resulting in a deep thread profile. A single lead thread, meaning that one revolution advances the screw one pitch. (Pitch is equal to 1 divided by the number of threads per inch. For a screw with 10 threads per in., one revolution will advance the screw 1/1O in. into the wood.)
The deep thread form provides superior resistance to pull-out. This design feature is commonly called a Lo-Root® or Production Screw.
