Thread Types

Deep (Coarse) The preferred choice for most woodworking applications. Agressive threads maximize holding power in softwoods, particle board, and MDF board.

Type A  Traditional sheet metal thread. Good for multiple applications in wood and metal and commonly used in harder woods to prevent splitting.

Twin Fast  Double lead thread decreases drive time compared to single lead thread designs. Good for hardwood fastening applications involving longer length screws.

Machine Screws  Standard machine screw threads to fit mating part applica tions such as mounting drawer pulls.

Features

Nibbed Flat Head  Built-in Nibs under the head assist the fastener to self-countersink the screw head without pre-boring.

Serrations  Locking serrations on right-angle screw heads promote the fastener to secure its position and decrease the potential of "backing out."

Self-Drill Point  Self-drill points are designed to drill in metal reducing tapping torque and the tendency to “strip-out.” Point type depends on material thickness.

Type 17 Point  The self-drilling point for wood applications. Prevents splitting and bursting of wood particularly for softwoods, particle board, and MDF board.

Sharp Point  Tapered points on deep threaded screws for thin material applications allow fastener to pierce surface for easy starting.
