Why this one
Ball point tip
The ball point tip lets you approach the fastener off-axis, up to 25°, while keeping the bit seated in the recess. That helps when space is limited.
100 mm reach
At 100 mm (3.9 in) long, it reaches past brackets, housings and covers without stacking extensions onto your ratchet.
S2 bit, chrome vanadium body
S2 steel bits are pressed into a chrome vanadium socket with a matte finish, and a ball retention groove helps it grip the square drive.
Sizes 3 to 12 mm
Sold individually in sizes from 3 to 12 mm on a 3/8 inch square drive, so you can replace one bit or fill a gap in your tray.
Read the full description
Larger metric hex fasteners carry higher torque loads, so the bit socket that drives them needs to maintain solid engagement even when access angles are less than ideal. This Teng Tools 12 mm ball point long hex bit socket lets you approach the fastener off-axis while the ball geometry keeps the bit seated in the recess, reducing the chance of cam-out or rounding.
The 100 mm (3.9 in) overall length reaches past brackets, housings, and covers without stacking extensions onto your ratchet. The 3/8 inch square drive fits directly into the ratchet, flex head, or torque wrench you already carry — no extra adapters to add play to the connection.
This is a single 12 mm socket, sold individually. That is an advantage when you need to replace a worn bit, fill a gap in your tray, or dedicate a specific size to a workstation. Automotive shops working on European sedans and SUVs will reach for 7 mm through 12 mm hex sockets regularly — brake calipers, engine covers, and transmission housings all use fasteners in this range.
Weighing 123 g, the tool is compact enough for a belt pouch or a mobile service cart. The ball point tip also helps protect plated and painted fasteners by distributing contact across the radius rather than concentrating force on sharp corners.
