## Abstract

A tool comprises a handle and a tool head at an end of the handle. The tool head has a channel for receiving a fastener. There is a resilient member disposed along a length of an inner surface of a wall defining the channel. The resilient member may be retained by a recess in an edge of the wall defining the channel. The channel may be defined by a first wall and a second wall and a web extending between the first wall and the second wall. The resilient member may be disposed along an inner surface of the first wall. There may be a lip extending along the second wall. The channel may alternatively be defined by a substantially tubular wall. The resilient member may be a spring disposed along an inner surface of the substantially tubular wall.

## Claims

### Claim 1

A tool for releasably holding a fastener, the tool comprising:
a handle defining a handle axis; and
a tool head connected to an end of the handle, the tool head having a channel for receiving a fastener, the tool head comprising:
a first flat wall, a second flat wall, and a third flat wall, each of the first and second flat walls connected to and extending perpendicularly away from the third flat wall and parallel to the handle axis to define the channel, the channel defining a longitudinal channel axis,
a spring disposed along a length of an inner surface of the first flat wall, the length being parallel to the longitudinal channel axis, the spring received in a first notch at a first end of the inner surface and in a second notch at a second end of the inner surface, the spring configured to engage and hold the fastener against the second flat wall, and
a lip disposed along a longitudinal length of the second flat wall, the longitudinal length being parallel to the longitudinal channel axis, the lip extending perpendicularly away from the second flat wall and toward the first flat wall to define a distal portion of the channel.

### Claim 2 (depends on 1)

The tool as claimed in claim 1 wherein the spring is configured to exert a force perpendicular to the second flat wall.
