Mixed Screwdriving Set - 30 Piece

This set includes Phillips, Pozidriv, TORX, and Slotted bits, covering a wide range of common domestic and light professional screws. It also includes nut setters for nuts and bolts.

The magnetic holder is designed for standard use and provides good grip. For extremely high-torque applications or continuous impact use, a dedicated heavy-duty magnetic holder or direct insertion into an impact driver might be preferred.

The connectable case system is designed specifically for IRWIN® branded cases. Compatibility with other brands is not guaranteed.

The product description does not specify impact rating for the bits. While the magnetic torsion holder may offer some benefit, for consistent use with high-torque impact drivers, it is recommended to use bits specifically rated for impact use.

Keep the magnetic tip clean and free of metal shavings. Avoid prolonged exposure to strong magnetic fields from other sources. Wipe dry after use.

Pozidriv (PZ) bits have four additional smaller ribs between the main flutes compared to Phillips (PH) bits. This design reduces cam-out (the bit slipping out of the screw head) and allows for higher torque transfer, making them preferable for many modern screws.

No, this set includes screwdriver bits and a magnetic bit holder. You will need a separate screwdriver handle or power drill to use the bits.

Ensure the bit's hex shank is clean and dry. Check for any damage to the bit's end or the holder's magnetic tip. The torsion feature might require a specific seating depth; reinsert firmly.

Check for any debris obstructing the latch mechanism. Gently flex the latch while opening/closing. If persistent, a small amount of lubricant on the hinge point might help, but avoid getting it on the bits.

Wipe bits dry immediately after use and store them in the case in a dry environment. If rust is minimal, a light application of oil (e.g., WD-40) followed by a thorough wipe-down can remove surface rust. For significant rust, consider replacement.

Ensure the locking tabs on both cases are clean and free from obstruction. Align the cases carefully before attempting to lock them. Ensure you are using compatible IRWIN® cases designed for this system.
