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). Specifications: • Size: #10-16 • Length: 2" • Head Style: HWH #3 Point • Load Bearing Area: 1-1/2" • Drilling Capacity: .150" • Aplication Use: Steel and Aluminum Features: • Self-drilling point • Higher hardness (HRC 52 min.)point and lead threads • Lower-hardness (HRC 28 – 34)load-bearing threads • Silver Stalgard® multi-layered corrosion resistant finish
