A nosepiece for fastener driving tools with a contact surface for engagement with the workpiece with a rounded profile to facilitate driving fasteners at an angle into the workpiece. Preferably, the contact surface has a first radially innermost portion of the contact surface for engagement of the workpiece when a screw is being driven substantially normal to the surface of the workpiece and a second outer portion of the contact surface radially outwardly from the innermost portion which outer portion is adopted to engage the work surface when a screw is being driven at an angle other than substantially normal to the work surface, the characteristics of the innermost portion of the contact surface and outermost portion of the contact surface varying such that the outer portion provides resistance to slippage of the nosepiece on the work surface when a screw is being driven at an angle to the normal.
