DASBET Variable Pin Spanner Wrench Set 15Pcs — Adjustable 1-1/4"–5" with Replaceable Pins

DASBET Variable Cylinder Spanner Wrench Set 15Pcs is an adjustable pin spanner kit that fits pulleys, cams and round parts from 1-1/4" to 5" with replaceable pins for precise engagement.

This 15-piece DASBET pin spanner set is built for mechanics, hobbyists and DIYers who need a compact, adjustable solution for holding, installing or removing slotted and holed pulleys, camshaft collars and similar round components. The kit includes a 12-inch holder compatible with 1/2" drive ratchets, a selection of seven pin diameters, and a durable storage case that keeps each piece organized for transport and long-term use.

How does the adjustable range help with different pulley sizes?

The wrench’s adjustable arm expands from 1-1/4" (3.2 cm) up to 5" (12.7 cm), allowing it to engage a broad variety of pulley diameters without needing multiple fixed tools. A single adjustment bolt secures the arm at the desired span so pins stay aligned under load.

• Adjustable span: 1-1/4" to 5" (3.2–12.7 cm)
• Single bolt lock for stable positioning
• Works with multiple pulley profiles that have slots or holes

Which pin sizes are included and why do they matter?

The set includes pins in seven diameters—3.5mm, 4mm, 4.5mm, 5mm, 6mm, 6.5mm and 10mm—so you can match the pin to the component’s hole or slot for a secure fit that prevents slipping. Choosing the correct pin reduces wear on both the tool and the part and improves torque transfer during removal or installation.

• Seven pin sizes for broad compatibility with fasteners and collars
• Interchangeable pins stored in clearly labeled slots
• Helps prevent rounding of slots and holes by ensuring correct fit

Can I use this with my existing ratchet or breaker bar?

Yes—the main 12-inch pin wrench is designed to accept a 1/2" drive ratchet or breaker bar, giving you extended reach and greater leverage when loosening tight parts. That compatibility makes the set practical for garage work without needing a dedicated handle.

• 12" (30.5 cm) holder with 1/2" drive attachment point
• Improved reach for recessed or awkward components
• Works with standard ratchets and breaker bars for added torque

What sorts of jobs and vehicles is this set suitable for?

The DASBET variable pin spanner is built for automotive and small-engine tasks: camshaft pulleys, crankshaft pulley holders, shock collars, threaded collars, and other slotted or holed round parts. It’s useful on motorcycles, scooters, bicycles and cars where OEM components often require pin engagement.

• Common use: camshaft and crankshaft pulley work
• Also fits collars, threaded rings and accessories with pin holes
• Compatible across bikes, motorcycles, scooters and cars

Who is this for: The DASBET 15-piece variable cylinder spanner wrench set is aimed at professional technicians, backyard mechanics and DIY maintainers who need a flexible, space-saving tool to handle a variety of pulleys and collars. If you value a single adjustable tool that adapts to multiple pin-hole patterns and pairs with your existing 1/2" drive tools, this kit reduces the need for many fixed spanners while keeping everything protected and organized in a heavy-duty case.
