Abstract
A tool is adapted for rotating a threaded fastener having a plurality of circumferentially arranged flat areas separated by respective points. The tool includes a handle having first and second opposing ends. At least one of the first and second ends defines a fastener-receiving opening. A plurality of cam surfaces are formed at the fastener-receiving opening, and are adapted for operatively engaging respective flat areas of the fastener. A plurality of point pockets are formed between respective cam surfaces, and are adapted for receiving the points of the fastener to preserve the points when the fastener is rotated by the tool.

A tool adapted for rotating a threaded fastener having a plurality of circumferentially arranged flat areas separated by respective points, said tool comprising:
- (a) a handle having first and second opposing ends;
- (b) at least one of said first and second ends defining a fastener-receiving opening;
- (c) a plurality of cam surfaces formed at said fastener-receiving opening and adapted for operatively engaging respective flat areas of the fastener;
- and
- (d) a plurality of point pockets formed between respective cam surfaces and adapted for receiving the points of the fastener to preserve the points when the fastener is rotated by said tool.
A removable socket for being attached to a handle of a tool adapted for rotating a threaded fastener, the fastener having a plurality of circumferentially arranged flat areas separated by respective points, said socket defining a fastener-receiving opening, and comprising a plurality of cam surfaces formed at said fastener-receiving opening and adapted for operatively engaging respective flat areas of the fastener, and a plurality of point pockets formed between respective cam surfaces and adapted for receiving the points of the fastener to preserve the points when the fastener is rotated by the tool.
A method for preserving a surface finish on a threaded fastener, the fastener having a plurality of circumferentially arranged flat areas separated by respective points, said method comprising the steps of:
- (a) applying a tool to the fastener, the tool having at least two cam surfaces adapted for operatively engaging at least two flat areas of the fastener;
- and
- (b) pivoting the tool to rotate the fastener in one of a clockwise and counterclockwise direction such that no portion of the tool engages the points of the fastener during rotation.
A method for preserving a surface finish on a threaded fastener, the fastener having a plurality of circumferentially arranged flat areas separated by respective points, said method comprising the steps of:
- (a) applying a tool to the fastener, the tool having a protective coating formed on at least two cam surfaces adapted for engaging at least two flat areas of the fastener;
- and
- (b) pivoting the tool to rotate the fastener in one of a clockwise and counterclockwise direction such that no portion of the tool engages the points of the fastener during rotation.
