6 Pack Small Block Ford Bellhousing Bolt Kit 289 302 351W

These bolts have a serrated flange that grips into the surface and doesn't let go! They are made from a SAE J429 Grade 5 material, and can withstand a minimum of 120,000PSI! Flange Bolts are identified by the built-in washer under the head that acts to distribute the clamping load over a greater area. They are designed to provide the same holding power as if you were to use a washer. The zinc plating makes them highly resistant to corrosion, with a shiny silver finish. These bolts are superior to original or OEM product, and are made to withstand high strength and extreme conditions, generally found in motorsports! High quality commercial grade bolts for less!
