Description: |
| This is an improvement—to make it stronger—to patent 179,695 which was a screwdriver designed for the screw of patent 145,411. The screw and accompanying screwdriver are known variously as Frearson or Reed & Prince drive. They are remarkably similar to, but incompatible with, Phillips. Reed & Prince screws and their accompanying drivers are popular with boat builders because they are considerably more resistant to camming out but it is more difficult to insert the screwdriver into the screw slot.Frearson drive screw were manufactured by Reed & Prince Mfg. Co., Worcester, Mass. We're not sure who manufactured their screwdrivers. The screws fell out of production during the 1970s or '80s, and Reed & Prince went bankrupt in the late 1990s. A new "Reed & Prince Mfg. Corp." was created and bought some assets including the name. Frearson / R&P screws and matching hex-drive bits are again in production and remain popular in the marine industry. |
