Pin spanner set Wiha 03992 Classic Holder, 6 pieces, pin-type wrenches for round fasteners

Wiha 03992 Classic Holder pin spanner set contains six pin-type wrenches designed to engage round, recessed or slotted fasteners where conventional spanners cannot be applied. The set's paired pins provide positive contact with retaining rings, collars and special fittings, enabling controlled loosening and tightening in maintenance, assembly and repair tasks. Tools are stored in a compact holder for organized transport and quick selection.

Advantages

The six-piece arrangement covers a range of pin spacings to fit different diameters of round fasteners. Hardened steel pins and precision-machined heads ensure accurate engagement and reduced slipping. The holder keeps the set compact and arranged for fast identification and safe storage. The pin-type design allows access to recessed fittings and limited-clearance locations that cannot be reached with open-end or box wrenches.

Suitable for

• Loosening and tightening retaining rings and circlips with pin holes
• Servicing bearings, collars and shaft-mounted fittings
• Assembly and disassembly of machinery with recessed fasteners
• Workshop maintenance and field service tasks requiring compact tools

Key specifications

• Number of pieces: 6
• Tool type: pin spanner wrenches with paired pins
• Holder: compact storage holder for organization and transport
• Material characteristics: hardened pins and corrosion-resistant finish on heads
• Application range: suitable for round, recessed or slotted fasteners with various pin spacings

How to use

Select the pin spanner whose pin spacing matches the holes or slots on the fastener. Insert the paired pins into the corresponding holes, ensuring both pins seat fully to avoid slipping. Apply steady torque by turning the wrench handle in the required direction to loosen or tighten the fastener. For confined spaces, position the holder to keep unused tools secure and work with controlled, even force to prevent damage to the fastener or pins.

Recommendations

Inspect pins before use and replace any tool with worn or damaged pins. Use appropriate hand force and avoid impact loading; do not use the pin spanners with power tools. Store tools in the holder to protect pins and maintain correct pin spacing. For corroded or stuck fasteners, apply penetrating lubricant and allow time to work before attempting to turn the fastener.
