Gibraltar 23050.0012 Male Spherical Washer 12mm Type C

Product Description

The GIBRALTAR 23050.0012 is a Type C male spherical washer designed for use with 12mm bolts. Made from case hardened steel, this metric fastener component provides a self-aligning bearing surface that compensates for angular misalignment between a bolt and its mating surface. The male spherical washer works in tandem with a corresponding female spherical washer to correct shaft or bore misalignment up to 3 degrees. It measures 13mm inside diameter, 24mm outside diameter, and 4.6mm thick, with a 17mm spherical radius. Licensed tradespeople and maintenance technicians working on industrial machinery, structural assemblies, and mechanical systems rely on this component for precise fastener seating.

This washer is suited for metric bolted assemblies in industrial, mechanical, and structural applications where angular correction is required. It is specified under DIN 6319, the standard governing spherical washers for use with bolted connections. Typical installations include machinery mounts, conveyor systems, shaft flanges, and structural steel connections where surfaces are not perfectly parallel. The Type C designation indicates the male-profile geometry, intended for pairing with a Type D female spherical washer to form a matched set.

Key Features

• Type C male spherical geometry provides up to 3 degrees of angular correction
• Case hardened steel construction for durability under high clamping loads
• Conforms to DIN 6319 fastener standard for metric spherical washers
• 13mm inside diameter fits 12mm bolt shafts with standard clearance
• 4.6mm thickness and 17mm spherical radius for precise mating surface contact
• Designed to pair with a Type D female spherical washer in matched assemblies

Compatibility

Designed as an OEM-style and aftermarket replacement for DIN 6319 Type C male spherical washers used in 12mm metric bolt assemblies requiring angular alignment correction.

Installation Notes

Installation is performed by maintenance technicians and millwrights working on bolted mechanical assemblies. Always de-energize and lock out machinery before servicing fastener components. Pair this Type C male washer with a matching Type D female spherical washer to achieve proper spherical seating. Torque the fastener assembly per the applicable engineering specification for the bolt grade and application.
