Bsc Preferred 153896 Impact Bit Set 4pc 5/16 Hex

Product Description

The BSC PREFERRED 153896 is a 4-piece hand impact driver insert bit set designed for use with hand impact drivers in mechanical and general trade service applications. Built around a 5/16 inch hex drive shank, this set delivers the driving torque needed to break loose stubborn fasteners without requiring pneumatic or powered tools. The set includes four insert bits covering both slotted and Phillips head configurations, making it a compact, task-ready kit for technicians who work in tight spaces where a full impact gun is impractical. HVAC, plumbing, and general maintenance professionals will find this set useful for panel fasteners, equipment covers, and access hardware.

This bit set is intended for use with hand impact drivers in residential and light commercial service environments. It is well suited for removing and reinstalling machine screws and slotted fasteners commonly found on equipment enclosures, electrical panels, and mechanical assemblies. The compact insert bit format means bits seat directly into a standard hand impact driver without adapters, keeping the tool profile low in confined areas. Per the input data, this set is specifically designed for use with the Master Mechanic Hand Impact Driver, model TV 150-706.

Installation Notes

Insert bits should be fully seated in the driver chuck before use. When driving or removing fasteners with a hand impact driver, strike the driver handle squarely with a hammer to transfer rotational force without damaging the fastener head. Always confirm the fastener type and size before selecting a bit to avoid cam-out or fastener damage. No power source is required, but standard hand tool safety practices apply.
