Tap-Flex® Thread-Forming Structural Screws

Amongst the vast selection of quality metal fastening systems and within the Elco line of metal fasteners can be found the Tap Flex Thread-forming Structural Screws. These are just one of the many products that Power Bolt and Tool insists on keeping in stock because of the high demand for these types of anti-corrosion fasteners.

WHEN DO YOU NEED TO UTILIZE THE TAP FLEX THREAD-FORMING STRUCTURAL SCREWS?
When you need a construction screw that is going to provide you with the strength and ductility that your project demands, then you need to rely on the dynamic treat engagement ability that this type of metal fastening system offers. Its performance is as a result of the patent pending E-form. This design offers some very significant and important advantages, all based on its technology.

THE IMPRESSIVE DESIGN OF TAP FLEX

These Elco metal fasteners are first subjected to the ultra-modern Flex Technology® of dual hardening where it is needed the most. With a minimum of HRC52 rate of hardening for the E-Form five-lobe lead tapping threads, it lends to the ease of installation. Reduced hardness is created to a HRC34 level or below in the load bearing sector of the screw, which meets the standards of the Grade 5 ASTM A449 for strength and ductility. With this composition of design, it wards off the possibility of structure failures and embrittlement. The end result is a completed project that is going to be comprised of longevity, durability and be impressive in appearance.

SAVING TIME WITHOUT COMPROMISE
Productivity without compromising integrity and durability of any construction project is the key to success. The Tap Flex Thread-forming Structural Screws are built with this in mind. The use of these Elco metal fasteners means no need for thread tapping procedures and is compatible with standard nuts and washers if the need is there for these.

HOW WILL TAP FLEX MEET YOUR EXPECTATIONS?

During use you will not have to deal with the build-up of friction or over use of drive torque. The precision design of this metal fastening system reduces the need for re-application and waste. Longevity is enhanced with the resistance these screws provide to vibration or thermal changes. Their anti-corrosion properties based on the quality alloy they are comprised of and further protection with Silver Stalgard® means no breach in their integrity or marring of appearance. The two major requirements of a top performing screw are met with easy application and remaining in place.

MULTI SIZE CHOICE

There will be no need for concern in meeting the metal fastening system size requirements of your project with the large range of choices between 3/8”, ½” and 5/8” diameters and lengths of 1 ½”,2” or 2 ½” . All with a hex washer head style.

Power Bolt and Tool knows that no construction job can be put on hold simply because of lack of products and equipment. Knowing the needs of the construction industry is a priority that we as construction providers take seriously. We make every effort to see that no tradesman ever has to be delayed in their responsibilities because of lack of supplies. When the call goes out for the Tap Flex Thread-forming Structural Screws we are ready to respond.

EXCLUSIVE TAP FLEX TECHNOLOGY® PROCESS
The Tap Flex structural screws undergo the special Flex Technology® dual hardening process. The lead tapping threads of the fasteners are selectively toughened to a minimum of HRC 52, which eases installation. The load-bearing part of the screw is held at, or below, the critical HRC 34 level.

The reduced hardness level of the structural screws effectively meets the Grade 5 ASTM A449 standards for strength and ductility. This makes the screws super strong and helps prevent embrittlement and other structural failures. In addition, the screws have a very long life and promise high performance in the field.

FEATURES AND BENEFITS OF TAP FLEX STRUCTURAL SCREWS
The screws eliminate thread-tapping operations.
E-Form configuration of the fasteners overcomes friction build-up and reduces the drive torque. This ensures that the screws have a long life.
Roll forms own work-hardened thread in order to resist the loosening that is usually caused by thermal changes or vibration.
Tap flex fasteners provide enhanced pullout performance.
The screws are well suited for metal applications like aluminum and steel.
The Flex Technology® heat treat provides the needed strength and ductility.
These structural screws are as good as immune to the delayed embrittlement failures.
The Stalgard® GB coating gives the screws as much as 1000 hours of salt spray resistance (per ASTM B117).
If required, the screws accept standard washers and nuts.
