The WIHA 74018 is a standard slotted power screwdriver bit designed for use with power drivers and impact-rated tool holders in professional trade and industrial settings. Built from steel, this bit measures 2 inches overall length with a 1/4 inch blade width, making it a direct-fit for standard slotted fastener applications. Sold in a pack of 10, it suits electricians, HVAC technicians, and general trade professionals who cycle through bits regularly and need consistent, reliable replacements on hand. The 1/4 inch hex shank is compatible with standard power bit holders.
This bit is suited for residential and commercial service work where standard slotted fasteners are encountered — including panel cover screws, junction box hardware, equipment access panels, and general fixture mounting. The 2 inch overall length provides enough reach for most recessed or countersunk fastener applications without requiring an extension. Each pack includes 10 bits, making it practical for stocking a service van or tool bag.
Designed as an OEM-style replacement power screwdriver bit compatible with standard 1/4 inch hex quick-change bit holders used in power drills, impact drivers, and right-angle drivers accepting standard slotted power bits.
Install into any power driver or drill with a standard 1/4 inch hex quick-change chuck or bit holder. Confirm the bit is fully seated in the holder before applying power to avoid cam-out or bit ejection. Match the blade width to the fastener slot width before driving to reduce fastener and tip wear. Replace bits showing visible wear or rounding on the tip to maintain proper torque transfer.
