Adjusting Screws-Nuts
Our rocker arm screws are made of a hot working tool steel that goes through a 4 stage heat treating process before it gets a specialty surface treatment to improve its wear resistance. This combination of materials and heat treat procedures makes the most durable and reliable screws available anywhere. All of our tool steel screws are manufactured with rolled threads and broached to accept an allen wrench. The screws are available with or without oil holes for pre-lube and oil grooves for pressure feed oiling. Manton makes custom screws on request, minimum quantities may apply. Depending on the style of screw and the application proper installation instructions will vary from one style screw to the next. Pressure fed adjusting screws need the oil band positioned properly so oil can flow around the oil band and into the side oil hole of the screw.
