L H Dottie 1158 Spanner Bit 1/4 Inch Shank 8x1

Product Description

The L H Dottie 1158 is a spanner bit designed for driving spanner-head (snake-eye) fasteners in electrical, low-voltage, and general trade applications. The bit features a 1/4 inch hex shank, making it compatible with standard power drill drivers and bit holders. It is sized for 8 x 1 spanner fasteners, which are commonly encountered during panel work, enclosure installation, and tamper-resistant fastener applications. Electricians, security installers, and general contractors rely on this bit type when working with tamper-resistant hardware in commercial and residential settings.

The 1158 spanner bit is suited for use on tamper-resistant screws found in electrical enclosures, access panels, restroom fixtures, and other installations where standard fasteners are replaced with security hardware. It is sold as a single unit and is intended for use in both hand drivers and power drill applications with a standard 1/4 inch quick-change chuck.
