This is a type of powder actuated drive pin designed for concrete applications. Each pin comes with a red plastic guide sleeve that helps center the pin in the gun barrel, reducing misfires and ensuring accurate placement. The guide sleeve also controls the embedment depth, preventing splintering or damage to the base material.
The color of the guide sleeve indicates the intended application: red for standard fastening, yellow for light loads, and black for heavy loads. The pins are electro-galvanized for corrosion resistance, and their smooth shank allows easy penetration into concrete.
These powder drive pins and powder driven pins are ideal for reliable, fast, and secure concrete fastening. Popular sizes are listed in the table below. Please contact us for more information and shipping options.
