Gibraltar Z8824 M24 Extra Thick Flat Washer Black Oxide

Product Description

The GIBRALTAR Z8824 is an extra thick flat washer designed for M24 metric fastener applications. Manufactured from case-hardened 1010 steel with a black oxide finish, this washer delivers increased load distribution and resistance to surface wear in demanding service environments. The additional thickness compared to standard flat washers makes it suitable for applications where standard hardware would deflect or embed under high clamping loads. Licensed trades and maintenance professionals working with structural fasteners, industrial machinery, and heavy equipment rely on this type of hardware for reliable joint integrity.

This washer is used in metric fastener assemblies requiring an M24 screw or bolt. The extra thick profile suits applications in fabrication, structural assembly, and industrial maintenance where load spreading across a larger bearing surface is necessary. The black oxide finish provides moderate corrosion resistance in dry indoor or controlled environments. Sold individually, it fits M24 metric bolt and screw hardware found in commercial construction, equipment manufacturing, and general industrial maintenance.

Key Features

• Extra thick 4mm profile for increased load distribution under high clamping forces
• Case-hardened 1010 steel construction resists deformation and surface wear
• Black oxide finish for moderate corrosion resistance in controlled environments
• M24 metric sizing with 25mm inside diameter and 40mm outside diameter
• Conforms to metric measurement standards (UNSPSC 31161807)

Compatibility

Designed as a metric-standard replacement flat washer compatible with M24 screws and bolts in industrial, structural, and mechanical fastener assemblies.

Installation Notes

Installation is performed by mechanics, millwrights, ironworkers, or any trade professional working with metric fastener assemblies. Ensure the mating fastener and joint surface are clean and free of debris before seating the washer. Standard hand tools and torque wrenches appropriate for M24 hardware apply. Follow applicable fastener torque specifications as defined by the equipment manufacturer or relevant industry standards.
