Coarse Thread
Provides best holding power for attaching to wood.For attaching drywall to wood studs and attaching fixtures to either material. |
|
|
|
 |
Type A (Self-Piercing Point) - Sharp Point
A thread forming screw for use in thin metal .015 to .050 thick. Used with drilled, punched or nested holes in sheet metal, resin impregnated plywood, and others. |
|
|
|
|
 |
Fine Thread
Provides best holding power when attaching to light- gauge steel. For drywall to 20-25 gauge metal studs. |
|
|
|
 |
Type AB - Sharp Point/Type B Threads
Thread forming screw combining locating point of Type A with thread size and pitch of Type B. Same normal limitations of Type B. |
|
|
|
|
 |
High-Low - Sharp Point
30º and 60º included thread angles. For attaching drywall to light-gauge steel studs or wood studs. Ideal for plastic, particle board, masonite and wood. Provides higher strip-out resistance. |
|
|
|
 |
Type B - Blunt Point
Thread forming screw for use in heavier metal .050 to .200 thick. For light and heavy sheet metal, monferrous castings, plastics, impregnated plywoods, and others. |
|
|
|
|
 |
High-Low - Blunt Point
30º and 60º included thread angles. For attaching drywall to light-gauge steel studs or wood studs. Ideal for plastic, particle board, masonite and wood. Provides higher strip-out resistance. |
|
|
|
 |
Type F
Thread cutting screw with machine screw thread and blunt tapered point, having multi-cutting edges and chip cavities. For heavy gauge sheet metal, lead, and others. |
|
|
|
|
 |
Twin Thread
Two helixes spiraling around the screw shank. Provides increased holding power and faster application speed. Provides higher strip-out resistance. |
|
|
|
 |
Type 17
Thread cutting screw for wood with a coarse tapping screw thread and a special long sharp point fluted to capture chips. |
|
|
|
|
 |
Self-Drilling Type
Allows drill and tap functions to be done in one quick operation. Metal up to .500 thick can be drilled and fastened easily. |
|
|
|
 |
Machine Screws
Used in a pre-tapped hole or with a nut. |
|
|
|
|
 |
Particle Board
Reduced body diameter causing less distortion of material. Greater pitch angle of threads resists pull out. Increased depth & wider spacing of threads minimizes crumbling of material. |
|
|
|
 |
Thread Forming
Precision thread forming screws that form mating threads to produce tight fastening assemblies. Triangular-modified thread body. Low driving torques and high holding power. |
