Big Timber Bronze Star Trim Head Screws 3 Inch T20 Drive 84 Count

Bronze trim head screws.

Steel

ACQ compatible.

Bronze ceramic triple‑layer coating provides corrosion resistance, especially in treated lumber; maintains finish outdoors.

Star drive (T‑20, six‑lobe) recess reduces cam‑out, improves torque transfer, and extends life of both screw and bit.

Heat‑treated hardened steel core gives high tensile and shear strength for structural integrity under load.

Features like under‑head cutting nibs help the screw self‑countersink, enabling a flush finish without damaging the wood surface.

Knurled shank & V‑cut thread notches reduce splitting, lessen insertion torque, and help draw wood pieces tightly together.

Sharp Type‑17 point helps start driving more easily—minimizing “walking” of the screw tip and often avoiding the need for pilot holes.
