T Handle Torx Key Wrench (T20 4.0x100)

The small Torx keys here sit on 75mm shafts, T20 and T25 on 100mm, the middle sizes on 150mm and the largest on 200mm. That reflects where each size is actually used — larger fixings go into larger assemblies, and larger assemblies recess their fasteners deeper. Matching the reach to the size means the tool gets to the screw it was made for without being unnecessarily long and whippy on small work.

T20 appears on appliance and equipment casings, vehicle interior and body fixings, machinery covers, furniture fittings and light construction screws.

It is worth remembering that Torx sizes are absolute rather than approximate. A T15 dropped into a T20 recess has visible free play and will round the points; a T25 will not enter at all. Unlike a hex key, where a slightly small key will still turn a fastener badly, Torx either fits or it does not — which makes a complete set genuinely necessary and makes identification easy.

The T-handle keeps the key square in the recess and lets the shaft be spun between the fingers once a screw is loose.

The material is forged chrome vanadium steel, hardened and tempered, with a satin finish and chrome plating for corrosion resistance.

The buyers are vehicle and motorcycle technicians, appliance repairers, furniture and cabinet fitters, machinery and equipment fitters, maintenance staff, and hardware dealers.

Two habits. Seat the key fully before turning, since a Torx key part way in bears on the tips of its points. And stop when a fastener seats rather than when it feels tight — Torx does not cam out, so it will keep applying torque until the thread gives, with no warning of the kind a cross-head provides.
