Serrated Flange Screws
Vibration and shock love to back fasteners out. Serrated flange screws bite in and lock when seated so your joints stay tight without extra washers. The built-in flange helps cover hole size variation for faster assembly on brackets, frames and equipment. Go Grade 8 when you need max clamp load, Grade 5 for solid everyday repairs.
