SCREW TYPE FASTENERS
Hex Lag Screws
Lag screws, also called lag bolts or coach screws, are large wood screws. The head is external hex and are driven with a wrench. Used for lag together lumber for framing, machinery to wood floors, and other heavy duty applications.
Self-drilling screws have a sheet metal thread with a self-driller cutting (TEK) point to pierce through 20 to 14 gauge metals. The higher the TEK number, the larger the drill point to pierce heavier gauge metals.
Sheet Metal Screws / Self Tapping Screw
Sheet metal screws (SMS) have sharp cutting threads that cut into sheet metal, plastic or wood. They have a fully threaded shank and sometimes have a notched point at the tip to aid in chip removal during thread cutting.
A machine screw is a screw or bolt with a flat point. Available in a variety of drive types and heads, they fit a wide variety of applications. Often driven into tapped holes. Used with nuts and washers, also known as “stove bolts” or “stovers”.
Particle Board Screws
Also known as Chipboard Screws. Typically used where speed of assembly is required. No drilling or punching required before use.
Used for heavy duty construction work to fix wood to wood or metal to wood. They are designed with a hexagonal head and, therefore, require a wrench or socket spanner to be tightened or unscrewed.
