To improve the waterproof performance of washers used on extra-long sharp point self-tapping screws, especially in roofing or outdoor applications, consider the following:
Use high-quality EPDM rubber washers known for their weather resistance, ozone resistance, and durability.
Choose metal + EPDM bonded washers to enhance sealing strength and prevent deformation under pressure.
Ensure the washer fits precisely with the screw head for maximum coverage and seal.
Apply proper installation torque to compress the washer fully without over-tightening, ensuring a tight seal.
Inspect regularly for aging or cracking, especially in outdoor environments, and replace washers when needed to maintain waterproofing.
