Common Problems Associated with Standard Fasteners: Head separation due to improper material selection, poor heat treat practice, or poor joint design. Fatigue failure caused by loss of clamp load, inadequate tightening or poor joint design. Cracked or split washers and nuts due to improper material selection, poor material quality or poor heat treat practice. Stripped nuts caused by improper strength grade selection, poor heat treat practice, or inadequate nut design. Rust and corrosion caused by improper selection of materials and plating for a specific corrosive environment or poor joint design. The Solution: L9 Hex Cap Screw Up to 28% thicker heads for more wrench contact and less slippage. Radius under cap screw head adds strength. Smooth washer bearing surfaces distribute loads uniformly and reduces brinneling. Plated finish assists torquing. Heat treating helps prevent splitting and stripping. All components are protected by a Yellow Dichromate finish for maximum corrosion resistance.
