Flat Head Socket Head Cap Screws

Need a flush, snag-free fastener that still pulls hard? Flat head socket cap screws countersink at 82 degrees for clean seating, with deep hex sockets for solid key engagement. Choose coarse for general assembly, fine for higher clamp load and vibration resistance. Go zinc plate for corrosion, black oil for shop builds, 18-8 stainless for wet service, metric in 10.9-12.9.
