Screwdriver Bit Set Stanley FATMAX FMMT82827-1 — metric Hex and Slotted bits, shank 1/2" (25.4 mm), boxed

Stanley FATMAX FMMT82827-1 is a boxed screwdriver bit set that contains a range of metric slotted and metric hex bits designed for mechanical, assembly and repair work. The set includes slotted bits in sizes 4, 4.5, 5, 5.5, 6, 7, 8, 10 and 12 mm and metric hex bits covering 4–14 mm as listed by the manufacturer. All bits are supplied with a 1/2" (25.4 mm) shank suitable for compatible bit holders and ratchets. The compact boxed format keeps the components organised and accessible on the workbench or in a tool bag.

Advantages

The set consolidates commonly used metric slotted and hex drive tips in one boxed kit, reducing time spent searching for the right size during mechanical and assembly tasks. The 1/2" (25.4 mm) shank format ensures compatibility with a wide range of half-inch bit holders and ratchet adaptors. Supplied in a box, the collection is easier to store and transport compared with loose bits, while the range of sizes covers small detail work up to larger hex fasteners.

Suitable for

• General mechanical maintenance and repair
• Assembly of machinery and equipment using metric fasteners
• Automotive and workshop tasks requiring metric hex and slotted tips
• Field service work where a boxed, organised bit set is required

How to use

Select the required slotted or hex bit size for the fastener being worked on, insert the bit into a compatible 1/2" bit holder, adaptor or ratchet, and engage the drive with the fastener. Apply controlled torque appropriate to the fastener and material to avoid rounding or damage. After use, return bits to their designated positions in the box to maintain organisation and ease of selection for future tasks.

Usage recommendations

Use the correct bit size for each fastener to minimise damage. When working on precision or torque-sensitive assemblies, use a torque-controlled driver or torque wrench with the appropriate adaptor. Store the boxed set in a dry place to prevent corrosion and inspect bits regularly for wear or deformation before reuse.
