12-point sockets (bi-hex) 1/2", set of 21 pcs. in a case (8-36 mm) STT CR-V SERIES 11 - Stix Tool

12-point sockets 1/2" 8–36 mm, 21 pcs

STT CR-V SERIES 11 is a set of 21 12-point sockets (bi-hex / double hex) with a 1/2", designed for a wide range of assembly, service and repair work. The set includes sizes from 8 to 36 mm, allowing it to handle both small fasteners and larger connections found in vehicles, machinery and workshop equipment.

Versatile 12-point profile

The internal 12-point profile increases the range of applications for the sockets. In addition to 12-point fasteners, it can also be used with standard hex bolts and nuts and, when properly matched, with square-profile fasteners.

Twelve contact points also mean that the socket can be positioned on a hex fastener in more positions than a standard 6-point socket. This makes work easier, especially where the movement of the ratchet or wrench is limited.

The sockets are well suited, among other things, for work on suspension, braking systems, chassis, engine components, mechanical connections and general assembly and service tasks.

Secure fit on a 1/2" drive

The sockets feature a 1/2" square drive socket with a recess for the retaining ball of the drive. Once the socket is fitted, the retaining ball engages the recess, helping to keep the socket securely on a ratchet, torque wrench or other 1/2" drive tool.

This design reduces the risk of the socket accidentally slipping off during use while still allowing quick fitting and removal.

A good choice for torque wrenches

Each socket has a 1/2" square drive, so the set can be used with, among others:

• 1/2" torque wrenches,
• 1/2" ratchets,
• 1/2" drive extensions and universal joints.

The wide size range makes the set particularly practical for work requiring controlled tightening to a specified torque.

21 sizes from 8 to 36 mm

The set includes sockets in the following sizes:

8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 24, 27, 30, 32, 34 and 36 mm.

Sockets in sizes 8 to 22 mm are 38 mm high, while the larger sizes 24, 27, 30, 32, 34 and 36 mm are 44 mm high.

Each socket has an engraved size marking, making it easier to quickly identify and select the correct socket during work.

Chrome-vanadium Cr-V steel

The sockets are made of chrome-vanadium Cr-V steel, providing suitable rigidity and durability during regular workshop use. The chrome-plated surface makes the tools easier to keep clean and helps protect their surface during use and storage.

Case with each size clearly marked

The set is stored in a rigid carrying case with foam insert. Each socket has its own fitted slot marked with the corresponding size.

In addition, the inside of the lid features a printed layout diagram for all 21 sockets together with their sizes. This makes it quick to locate the required socket and easy to check that the complete set is back in place after use.
