Dril-Flex® fasteners are specially designed and processed to help prevent hydrogen-induced brittle failures. Each fastener undergoes a unique dual-hardening process to ensure the optimal combination of ductility and hardness required for maximum performance in the field.

Testing of this product, in accordance with ASTM standards, has proven that Dril-Flex fasteners provide the same resistance to hydrogen-assisted cracking (HAC) as a Grade 5 fastener.

Hydrogen-Assisted Cracking (HAC) refers to any time-delayed failure mechanism that is aggravated or accelerated because of the presence of hydrogen. Most self-drilling fasteners are case-hardened, which provides the necessary hardness for drilling and tapping, but leaves the screws vulnerable to HAC due to their high surface hardness.

Dril-Flex fasteners offer a unique dual-hardening process. The self-drilling point and lead tapping threads are selectively hardened to a minimum of HRC 52. The load-bearing portion of the screw is held at or below the critical HRC 34 level. This reduced hardness level also meets SAE J429 Grade 5 and ASTM A449 strength and ductility standards.

Dril-Flex fasteners are then coated with Stalgard® finish to provide superior corrosion resistance. Fasteners coated with Stalgard finish typically show no red rust or other base metal corrosion on significant surfaces even after 800 hours of 5% neutral salt spray exposure (ASTM B117).
