Fasteners & Bolts

CORTEX® by Fastenmaster

The Cortex Hidden Fastening System is the fastest, easiest way to hide fasteners in composite, capstock, and PVC decking boards.

Cortex offers a strong connection between the deck board and joist. It hides fasteners across the entire deck, first and last board, perimeter and stairs.

Cortex now comes with the following product enhancements:

  • TORX® ttap® Drive System: This system is almost impossible to strip-out. In addition, the stability button keeps the fastener straight through installation.
  • Modified Fastener: New thread design reduces installation torque and dramatically increases fastener strength. Length moves from 2 ½”.
  • Stronger Setting Tool: Optimized for extreme pro contractor use. Stronger bit material and industrial grade felt will enable you to install 350 fasteners on one Cortex Setting Tool.

Steelhead® Fasteners was formed in 1997 by the sales staff at a Washington State based STAFDA Distributor who desired to find a reliable source for high quality, yet affordable stainless steel and hot dipped galvanized collated fasteners. Bulk and hand drive nails were easy to find, but more and more of their customers wanted to utilize the pneumatic nailers they owned when the new generation building materials called for a particular specialty fastener. Taking their combined 45+ years in the industry, and the feedback from industry partners around the country, the professionals at Steelhead® Fasteners have developed a complete line of corrosive resistant collated nails and staples that meet the demands of the quality conscious end user.
