Frame bolts, also known as hex flange screws, are a one-piece hex-washer head bolt with a flat bearing surface. Frame bolts are commonly used on truck frames, giving them their name. The flange eliminates the need for a washer and helps to compensate when holes are misaligned. When used with a Grade-Gt lock nut, the frame bolt system resists bolt slippage by distributing the clamp load over a wide area. WINDO METAL offers frame bolts in both metric and SAE sizes and in a variety of grades including Grade-5, Grade-8, Grade-9, Class 8.8, and Class 10.9. Our finish offerings include furnace black, black phosphate, trivalent RoHS, and Zinc Yellow, however we’re able to custom coat any fastener through our in-house plating department. AFT is always here to help, so if you don’t see the exact frame bolt or size you need, please contact us for assistance. Carriage Bolt with Round Head
