Driver Bits

Frearson Driver Bits

Frearson screw-heads are much like a Phillips head. They also have cross-slots but are V-shaped with tapered sides. Although this screwdriver may fit into many different slots, it is best to use the driver that matches the proper size.

Phillips Head Drivers

Cross-head, or Phillips screw has an X-shaped slot and is driven by a cross-head screwdriver, designed originally in the 1930s for use with mechanical screwing machines, intentionally made so the driver will ride out, or cam out, under strain to prevent over-tightening.

Square Drive (Robertson) Bits

Jamestown offers many square drive screws, which have increased in popularity in the recent past because of the trend of do-it-yourself deck projects. These drives have a square head to grip the screw better on all four sides and provide better torque and range in size from 0 -3 and jumbo.

Slotted (Regular Driver Bits

Generally large, heavy-duty screws. The tip of the driver is flared so it is wider than the driver bar and can fit more easily into the screw. High quality drivers should be ground for all-around uniformity on the tip. The blade however should not taper too much from the tip because an improper taper can cause it to slip out of the screw slot. The blade of the screwdriver should fit snugly in the slot, and it should be as wide as the head of the screw to prevent it from slipping out of the slot and marring the project. It will also prevent damage to the screw's head and screwdriver tip.
