Ask the Fastener Expert: What are Combo Drive Barrels and Screws?

Combo Drive Barrels and Screws are a type of mating fasteners that collaborate to secure a specified length between the barrel's head and the mating screw's head, such as within a hollow door. Binding Posts and Screws find frequent application in conjunction with round or square metal tubes or pipes.

Within this extensive assortment of Combo Drives, the truss-style head stands out, presenting a broader and lower profile compared to the conventional round head. This unique head features a versatile combination drive, incorporating a combination slot and Phillips. The truss head design is specifically engineered to distribute holding pressure, thereby reducing the risk of crushing in thin and softer materials. Additionally, it provides an increased bearing surface, enhancing overall holding power. The screws adhere to a class 2A fit.

Combo Drive Barrels and Screws are offered in the following materials and finishes:

  • Steel: Zinc-Plated Finish, Zinc-Black Finish, Black Oxide Finish

  • 18-8 Stainless Steel: Passivated

  • 316 Stainless Steel: Passivated, Plain Finish, Black Oxide Finish

  • 410 Stainless Steel: Thru Hardened
