Set of tools in tray 4 for 2600A-US or 2600C-US

Torque is the bench mechanic’s quiet specialty. Carbon bars at 5 Nm, stem face-plates at 5–6 Nm, crank bolts at 35–50 Nm, rotor bolts at 5–6 Nm per rotor manufacturer’s spec; get any of them wrong, and the result is a customer ticket and a warranty claim. The SET4-2600AC Torque Tools and Pliers tray for the Unior 2600A and 2600C benches bundles the torque-and-precision-socket inventory into one foam-cut bench drawer: the 266B Electronic Torque Wrench, the full 1/4” and 1/2” socket range, Y-handle hex and Torx, and the everyday pliers.

What’s in the tray

Electronic torque wrench (the centerpiece):

• Electronic Torque Wrench 266B; covers 4.2–85 Nm. Spans rotor bolts (5–6 Nm) through crank bolts (35–50 Nm) and BB cup installs (35–50 Nm). For lower-torque carbon-bar work (2-20 Nm), shops typically pair with the matching 1–20 Nm wrench.

Y-handle wrenches:

• Y hex wrench (1781/2HX-US); 2/2.5/3 and 4/5/6 mm.
• Y Torx wrench (1781/2TX-US); T10/T15/T25.

1/4” socket system:

• Reversible ratchet 1/4” (188.1/1ABI-US)
• Extension bar 1/4” (188.4/2)
• Adaptor 1/4” (188.7/2)
• Socket 1/4”, 6-point (188/2 6P)

1/2” socket system:

• Swivel handle 1/2” (190.2/1BI-US)
• Extension bar 1/2” (190.4/1)
• Adaptor 1/2” (190.7/2)
• Socket 1/2”, 6-point (190/1 6P)

Hex sockets:

• Hex socket 1/4” (187/2HX); 1/4” drive hex sockets.
• Hex socket 1/2” (192/2HX); 1/2” drive hex sockets.
• Long hex socket 1/2” (192/2HXL); extended-reach 1/2” hex.

Torx sockets and bits:

• Screwdriver socket with TX profile 1/4” (187/2TX).

L-handle and ball-end hex:

• T-handle ball-end hex wrench (193HXS-US)
• Hex wrench (220/3); standard L-key.
• Hex wrench, long type (220/3L); long-arm version for reach.
• Ball-end hex wrench, long type (220/3SL); ball-end + long-arm.
• Wrench with TX profile and hole (220/7TX); security-Torx capable, T-handle.

Pliers (everyday workshop):

• Combination wrench, long type (120/1)
• Cable puller pliers with lock (1642.1/2P-US); locks onto cable end and holds while bolt is torqued.
• Combination pliers (406/1VDEBI); VDE insulated.
• Waterpump box joint pliers (449/1PYTHON-US); adjustable, with plastic jaw protection (449.1) for not marring component surfaces.
• Long-nose pliers with side cutter (506/1VDEBI); VDE insulated.

The tray ships with the empty foam shell (VL4-2600AC).

Why this is the precision tray

The 266B torque wrench is the line-item that justifies the tray cost. Calibrated torque wrenches separate professional service from amateur service in the bike industry; the difference shows up in carbon-component warranty claims, stripped crank bolts, and brake-caliper-bolt fatigue failures. The 266B’s dual-drive range (1/4” through 1/2”) covers the full bike-fastener torque band in one tool; the matching socket range completes the inventory.

For shops not adding the torque wrench, the SET1-2600AC general-tools tray covers everyday Hex and Phillips work without the torque element. The SET4-2600AC adds the precision-and-torque layer above SET1.

Compatibility

Sized for the bench-integrated 990WD7 drawer in the Unior 2600A and 2600C workbenches.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče, Slovenia, since 1919, and is the official technical partner of multiple World Tour and downhill teams. The 266B Electronic Torque Wrench is part of Unior’s calibrated-tool line; the bit-socket sizes are manufactured to DIN 7422 (hex bit socket dimensional standard).

Pro tip from our mechanics

SET4-2600AC is the tray that justifies the bench-and-cabinet investment by service quality, not by service speed. A torque-controlled crank install lasts the life of the crank; a feel-based install can fatigue the bolt in two years.
