Versatile 20-piece hex bit set

The DIYSELF 20-Hex set supplies 10 SAE and 10 metric sizes in a single pack. Bits range from 1.5 mm to 8 mm and 5/64 in to 5/16 in, each clearly marked for quick selection. The 1/4 in hex shank fits most drills and impact drivers. Professionals and DIY users gain a ready-to-use assortment for everyday fastening tasks.

S2 steel construction with magnetic tips

Premium S2 alloy steel and CNC-machined hardened tips resist wear and cam-out during repeated use. A built-in magnetic grip holds screws securely, reducing slippage on vertical or overhead work. The torsion zone absorbs sudden torque peaks, lowering the risk of bit breakage. Corrosion-resistant finish extends service life in demanding environments.

Extended reach for tight spaces

Two-inch bit length provides better access in recessed or confined areas common in automotive, furniture and electronics jobs. The set covers common hex socket screws without needing separate SAE and metric kits. Magnetic retention frees one hand for positioning workpieces. Builders needing specialised security bits or larger drive sizes will require a different collection.

Questions about this item

Will the 20-piece 2" S2 steel bit set work with my older 1/4" hex-shank impact driver?

Yes, the 1/4" hex shank fits standard chucks on most drills and impact drivers, including older models, so the 20 bits engage directly without an adapter.

How can I confirm the torsion zone is absorbing torque peaks during use?

The bit flexes slightly under sudden load instead of snapping, and the hardened S2 steel tip stays engaged in the fastener head without rounding off.

Which 20 sizes are included and is a case or holder supplied?

The set contains 10 SAE sizes from 5/64" to 5/16" and 10 metric sizes from 1.5 mm to 8 mm, each marked on the bit; no case or holder is included.
