35 Piece Bit Socket Set 1/4 and 3/8 Inch Drive

The Teng Tools TTBS35 is a 35 piece bit socket set on 1/4 and 3/8 inch drive, organised in a TT-Series module size 1 tool tray. Teng Tools describes it as holding all the most commonly used screwdriver, hex and TX bits, in metric and AF sizes, for automotive, industrial and maintenance work.

The 3/8 inch drive side carries the hex bit sockets, which is what most people mean by an allen wrench socket set or an allen key socket set: AF sizes 1/8, 5/32, 3/16, 7/32, 1/4, 5/16 and 3/8 inch, and metric sizes 3, 4, 5, 5.5, 6, 7, 8, 10 and 12 mm. A hex head socket set on a ratchet turns a long screw home faster than a loose L key.

The 1/4 inch drive side carries the TX bit sockets TX10 to TX40, Phillips PH0 to PH3, Pozidriv PZ1 to PZ3, and flat bit sockets including 4 mm and 7 mm. With a torx and hex socket set in one tray, most of the internal drive screws on a vehicle or a machine are covered from one drawer.

Two adaptors come with the set: a step up adaptor 1/4 inch F to 3/8 inch M and a reducing adaptor 3/8 inch F to 1/4 inch M. The bit sockets are chrome vanadium with a satin finish, according to Teng Tools.

The TT1 tray has a PS inlay with a marked position for every piece, so a missing size shows at a glance. It measures 265 x 142 x 50 mm (10.4 x 5.6 x 2.0 in) and weighs 1194 g (2.6 lb) with everything in place, and it lines up with other TT-Series trays in a toolbox drawer.

What you get: 35 pieces in a TT1 tray, made up of 1/4 inch drive TX, Phillips, Pozidriv and flat bit sockets, 3/8 inch drive hex bit sockets in AF and metric sizes, a step up adaptor and a reducing adaptor. Ratchet and handles are not included.

• A full torx socket set on 1/4 inch drive with TX10, TX15, TX20, TX25, TX27, TX30 and TX40, the commonly used TX sizes for automotive, industrial and maintenance work. Each bit is held in its own socket body, so it runs straight from a ratchet, a T bar or an extension without a separate bit holder, and a missing size shows as an empty place in the tray.
• An AF hex socket set on 3/8 inch drive in 1/8, 5/32, 3/16, 7/32, 1/4, 5/16 and 3/8 inch for imperial socket head and set screws. Working an internal hex screw from a 3/8 ratchet or breaker bar gives you more control over a tight one than a loose L key, and the short bit gets in where a long key arm cannot swing.
• A metric hex bit socket set on 3/8 inch drive in 3, 4, 5, 5.5, 6, 7, 8, 10 and 12 mm for metric internal hex fasteners. Together with the AF row, one tray answers both metric and imperial socket head screws, so you are not hunting through a drawer of loose keys for the one size the job needs today.
• Phillips PH0, PH1, PH2 and PH3, Pozidriv PZ1, PZ2 and PZ3, and flat bit sockets including 4 mm and 7 mm. Driving a screw from a ratchet gives more turning force and control than a screwdriver when a screw is tight or sits in a confined space. The sockets are chrome vanadium with a satin finish, according to Teng Tools.
• A step up adaptor 1/4 inch F to 3/8 inch M and a reducing adaptor 3/8 inch F to 1/4 inch M let either half of the set run from the ratchet you already have. Everything sits in a PS inlay in a Teng Tools TT-Series tray, module size 1 (TT1), 265 x 142 x 50 mm (10.4 x 5.6 x 2.0 in), weighing 1194 g (2.6 lb) loaded.
