Proper head style choice will ensure stability during driving, proper clamping and desire finished appearance.
THREAD FROM AND DIAMETER
The correct choice of thread form and diameter optimizes low installation torque with high pullout strength.
Plating & coatings provide lubricity during drilling and tapping as well as corrosion resistance.
The unthreaded portion of the point assures that drilling of the steel is completed before the threads begin tapping into the drilled hole.
The point is designed to efficiently remove material and precisely size the hole to the thread & precisely size the hole to the proper diameter of the thread.
* Drill capabilities may vary with special flute length.
A separate drilling operation is not necessary. However, specific installation procedures are necessary to insure correct fastening results and to achieve published performance values for each fastener.
Important: A 1900 to 2500 RPM screwgun rated at 6 amps or higher, equipped with a properly adjusted depth-locating nosepiece should be used to ensure proper fastening performance. During initial drilling, enough pressure must be applied while keeping the screwgun and fastener perpendicular to the work surface to prevent angle driving or walking. Drilling must be completed before the threads engage the material. It is essential to choose the correct fastener based upon the total thickness and type of material to be drilled and fastened for an application. Never overdrive the fasteners or install fasteners at an angle to the work surface as this may significantly reduce product performance or lead to failure.
