Magna Iso Temp bits are suitable for hard fixing. Ie. screwing into metal and peak torque applications. Magna is a leading brand of high quality Screw Driver Bits that are well-known within the industry for their durability. 

Screwdriver bits are typically made up of a shaft and a tip. A screwdriver bit's shaft is typically hexagonal in shape, with six flat sides. This shaft is fitted into the end of a screwdriver that has a bit holder. The shaft's shape prevents the bit from rotating within the bit holder. The tip end of a screwdriver bit may have many shapes.The bit's head is designed to fit into the head of a screw. As the screwdriver is spun, the bit rotates as well. This is what causes the screw to turn.

Head style: Phillips
Length: 89mm

Henry F. Phillips intentionally designed the Phillips screw driver to cam out when the screw stalled in order to prevent the fastener from damaging the work or the head and instead damaging the driver. Philips bits resemble a cross and are available in a variety of sizes.

Magna's ISO-TEMP Driver Bits are suitable for applying screws to a wide range of high wear applications including PVC profile, Timber, and particularly Aluminium and Steel when using self-tapping screws.
