8 Piece Adjustable Hook and Pin Wrench Set

Keep every hook and pin wrench you need in one organized tray. This 8-piece collection from Teng Tools covers three overlapping metric size ranges — 19–50 mm, 32–75 mm, and 50–120 mm — so you can service lock nuts, bearing retainers, slotted collars, and spanner-notch fasteners across a broad spectrum of diameters.

The three adjustable C-type hooks handle the bulk of the work, gripping into peripheral slots and notches with a secure, controlled bite. When the fastener calls for face-pin engagement instead, swap to the matching pin arm: 4 mm for the 19–50 mm range, 5 mm for the 32–75 mm range, or 6 mm for the 50–120 mm range. Dedicated 6 mm and 8 mm pins complete the lineup.

Every piece is made from chrome vanadium steel to DIN 1810, the standard that governs jaw geometry and pin placement for this class of hand tool. That translates to accurate fit, repeatable torque transfer, and long service life under professional use.

The molded TT1-size tray keeps all eight pieces visible and organized. It drops directly into compatible Teng Tools roller cabinets and service carts, eliminating loose-drawer hunting and making tool audits simple. Total set weight is 1210 g.

Ideal for automotive technicians adjusting wheel-bearing lock nuts, millwrights setting spindle preload, and hydraulic specialists working cylinder gland nuts — anywhere a metric lock nut or retaining ring demands a purpose-built wrench rather than an improvised solution.
