The KLEIN TOOLS C2355 is a 3.5-inch power driver bit designed for use with power drills and impact drivers in professional trade applications. Built for the demands of electrical, HVAC, and general mechanical work, this bit delivers consistent torque transfer in fastening tasks where a standard-length bit falls short. The 3.5-inch length provides added reach in recessed or tight-access fastening points without sacrificing control. Electricians, HVAC technicians, and plumbers routinely use extended driver bits like this one when working inside panels, enclosures, and equipment cabinets.
This power driver bit is suited for residential and light commercial installation work where extended reach is required. Common applications include securing junction box hardware, panel covers, equipment mounting screws, and fixture assemblies. The added length makes it practical for use in drill drivers and impact drivers across a range of fastening scenarios encountered in day-to-day trade work.
Designed as an OEM-style replacement or standard accessory bit compatible with 1/4-inch hex shank power drills and impact drivers commonly used in electrical and mechanical trade work.
Installation of fasteners using this bit should be performed by qualified trade professionals following applicable NEC or local code requirements. Ensure the driver tool is powered off or the battery is removed before changing bits. Use the correct bit tip size for the fastener head to avoid cam-out and fastener damage. Do not exceed the torque rating of the fastener or the drive tool.
