Unifix Hand Tools and Bits

It is used to tighten and loosen bolts and nuts without removing the wrench from the nut after each turn. The combination wrench has a ring end and an open end, so it fits both exposed nuts and tight spaces. The ratchet is useful in workshops, vehicle maintenance and machine assembly, where many screws of the same size are worked on.

Each drive has a different shape and must be used with the matching screw. A slotted screwdriver has a flat blade, a Phillips a cross-shaped tip, TX a six-point star and Pozidriv a cross with small notches. Using the wrong tip damages the screw head and makes the tool slip. When choosing, the screw drive comes first, then the tip size.

It indicates the bit shank: C 6,3 is the 6.3 mm hex shank, which is a quarter inch, and fits bit holders and handles of the same series. The 1/4 side is the one that goes into the chuck or screwdriver. Bits with SDS-Plus shanks have a different shape and are not interchangeable. Choosing the right shank avoids play and slipping during work.

A complete set covers the most used drives: slotted, Phillips, Pozidriv and TX. In kits such as the F99 sets, more drives come in the same assortment, while the set with a phase tester is useful for checking whether a circuit is live. Before buying, check which screws you use most often and whether you need insulated screwdrivers for electrical work, where the choice must comply with D.Lgs. 81/2008.

Insulated pliers are used for work on electrical systems and panels, where there is a risk of touching live parts. The handles have an insulating coating, but they must be checked before each use: if the sheath is cut, cracked or worn, the tool must not be used. Round-nose, long-nose or half-round pliers are used to bend, grip and hold wires and small parts. Choose the shape according to the space available.

Before use, check that the riveter is intact, with its parts tightened and rivets of the right size for the hole. Wear safety glasses, as fragments can come off during riveting and striking. For the hammer, check that the handle is intact and fixed to the head, and always strike with the flat face towards the workpiece, without using the head as a rest for other blows.

The Swedish pipe wrench, such as the I01 series, is used to rotate and grip pipes and rebar, with the grip tightening as it turns. The rebar-tying pliers, such as the E36-54 series, are used to cut and bend the iron wire used to tie reinforcement. They are tools for construction sites and plant installation, used by those who work with pipes, rebar and steel reinforcement.
