Bike Tool Set in Tool Tray — Sockets, Ratchets & Torque Wrench (1600SOS23)

A bike mechanic’s torque and socket inventory grows by accretion. The first 5 mm hex socket gets added when a fastener won’t accept a standard wrench; the second socket comes when an extension is needed; the third comes when the working angle won’t allow a straight pull. Within a year, the socket tray is full of mismatched-size singles. The Unior 1600SOS23 tray gets the shop to a complete sockets-and-ratchets inventory in a single purchase: Y-handle hex and Torx wrenches, 1/4” and 1/2” socket sets across the everyday metric range, swivel handles, ratchets, and both 266B electronic torque wrenches.

What’s in the tray

Y-handle wrenches:

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

Hex and Torx sockets:

• 1/4” hex sockets (187/2HX): 3, 4, 5, 6 mm
• 1/2” hex sockets (192/2HX): 6, 8 mm
• 1/2” long hex socket (192/2HXL): 10 mm × 64 mm
• 1/4” Torx sockets (187/2TX): T8, T10, T15, T25, T27
• 1/2” Torx sockets (192/2TX): T30, T40
• 1/2” Torx Plus socket (192/2TXP); for the Torx Plus T-flat profile (Bosch eBike Gen4 motor-mount bolts, premium-tier component fasteners).

Ratchets, extensions, and adapters:

• Reversible ratchet 1/4” (188.1/1ABI-US)
• Extension bar 1/4” (188.4/2): 1/4” × 100 mm
• Adaptor 1/4” - 3/8” (188.7/2)
• 1/4” 6-point sockets (188/2 6P): 7, 8, 9, 10, 11 mm
• 1/2” 6-point sockets (190/1 6P): 12, 13, 14, 15, 17, 18, 19 mm
• Swivel handle 1/2” (190.2/1BI-US): 1/2” × 450 mm
• Swivel handle 1/4” (188.2/2BI-US)
• Extension bar 1/2” (190.4/1): 1/2” × 125 mm
• Adaptor 1/2”-3/8” (190.7/2)

L-key sets and clip wrenches:

• Long-type hex wrenches (220/3L): 10, 12 mm
• Ball-end hex wrenches, long type on plastic clip (220/3SLPH-US)
• Torx wrenches with hole on plastic clip (220/7TXPH): TR8 through TR40 × 9

Electronic torque wrenches:

• 266B Electronic Torque Wrenches — 1/4” and 1/2”: the 1/2” unit spans 4.3–85 Nm and covers the high-torque bike-fastener range from rotor bolts (5-6 Nm) up through crank bolts (35-50 Nm) and BB cup installs (35-50 Nm); for lower-torque carbon-bar work (2-20 Nm) the tray includes the 1-20 Nm electronic torque wrench as well.

The tray ships with the empty foam shell (vl.1600SOS23, 564 × 364 × 30 mm) and the Made for Work label.

Where it fits

The 1600SOS23 fits the bench-corner role for shops that need a complete torque-and-sockets inventory in a single drawer. The two 266B electronic torque wrenches are the most cost-significant tools in the tray; pairing them with the matching socket inventory removes the typical “do I have the right socket for this torque value” question. For shops adding only sockets (not a torque wrench), an individual purchase of 187/2HX or 192/2TXP is the cheaper path; the 1600SOS23 is the bundle.

Companion trays:

• 1600SOS21; Hanger Alignment & Cable Pliers
• 1600SOS24; Cone Wrenches
• 1600SOS25; Crank, Cassette & Freewheel Tools
• 1600SOS26; Bottom Bracket, Spoke & Brake Tools
• 1600SOS27; Hex/Torx T-Handles & Screwdrivers

Compatibility

Fits the full-width drawer slot in Unior’s tool carriages: Hercules, Eurovision, Eurostyle, Euromotion, and Europlus.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and sponsors professional road and mountain-bike race teams. The hex/Torx sockets in this tray are manufactured to DIN 7422 (hex bit socket dimensional standard); the torque wrench is part of Unior’s calibrated-tool line with documented spec sheets.

Pro tip from our mechanics

The 266B torque wrenches are the tools in the tray most likely to pay back fastest. For crank installs, the 35–50 Nm range is what saves the bolt; for lower-torque carbon-bar work, the tray’s 1-20 Nm wrench takes over.

FAQ

Does the 1600SOS23 tray include a torque wrench? It includes two: both 266B electronic torque wrenches. The 1/4" unit covers 1–20 Nm for stems, cockpit hardware, and other low-torque fasteners; the 1/2" unit covers 4.3–85 Nm for rotor lockrings, crank bolts, and bottom-bracket cups. Each gives a target-torque warning by buzzer and two LED lights and works in peak-hold or track mode.

Do the electronic torque wrenches need batteries? Yes — each 266B runs on a single AAA battery, which is not included in the tray. Rechargeable AAA cells work. The wrench switches off automatically after 5 minutes idle, and Unior rates it for 10,000 cycles with a one-year warranty.

Which Unior tool carriages does this tray fit? The foam tray measures 564 × 364 × 30 mm and spans the full width of the drawer in Unior's tool carriages — Hercules, Eurovision, Eurostyle, Euromotion, and Europlus. Every tool has its own cut-out, so a missing tool is visible at a glance.

What socket sizes and profiles are in the tray? Hex sockets in 3, 4, 5, and 6 mm (1/4" drive) plus 6 and 8 mm and a 10 × 64 mm long socket (1/2" drive); Torx sockets TX 8–TX 27 (1/4") and TX 30/TX 40 plus a Torx Plus socket (1/2"); and six-point sockets in 7, 8, 9, 10, 11 mm (1/4") and 12, 13, 14, 15, 17, 18, 19 mm (1/2").
