The Stanley FATMAX FMMT82827-1 Hex Slot 4-12 mm screwdriver bit set contains a selection of hex and slotted bits with sizes from 4 mm to 12 mm. Each bit has a 25.4 mm (1") shank designed for compatibility with standard bit holders and quick-change chucks. Supplied in a compact box, the set is intended to provide a practical assortment of bit profiles for general fastening tasks in maintenance, assembly and repair work.

Advantages

The bits are manufactured to offer consistent fit in hex and slotted fasteners, reducing cam-out and wear during repeated use. The standardized 25.4 mm shank ensures stable seating in bit holders and power drivers. The storage box keeps the set organized and protects the bits from corrosion and damage when not in use. The combination of hex and slotted profiles in one set increases flexibility on site or in the workshop.

How to use

Select the correct bit size and profile for the fastener to avoid damage. Insert the 25.4 mm shank into a compatible bit holder, manual handle, or power driver, ensuring it seats fully. Apply steady torque appropriate to the fastener and material; for manual use maintain controlled pressure to prevent slipping. After use, clean the bits of debris or grease and return them to the storage box to preserve condition.

Recommendations

For best results use the hex bits for hex-head fasteners and the slotted bits only where slot-type fasteners are specified. Avoid excessive torque that can deform slotted heads; when using power drivers, set torque limits appropriate to the fastener material. Store the set dry and inspect bits periodically for wear; replace worn bits to maintain secure fit and reduce risk of fastener damage.
