Torx Flat Cylinder Socket Head

Cylindrical trim head bolts feature a narrow, cylindrical head that sits nearly flush for a clean, low-profile finish in applications such as decking, ceiling panels, or trim work. The head tapers or countersinks smoothly into the material, while specialized threads—such as a “twister thread”—assist in driving the bolt for a tight, gap-free fit.

A4 / 316 Stainless Steel fasteners are “marine grade” corrosion resistant; suitable for salt water applications. A4 fasteners also offer increased resistance to chemicals when compared with A2 stainless fasteners.
