1 1/4 Flat Washers Stainless Steel
Description
1 1/4" Flat Round Washers – Stainless Steel (Various Outer Diameters)
1 1/4" stainless steel flat round washers are engineered to fit imperial 1 1/4" bolts and screws, delivering reliable load distribution and surface protection in fastening assemblies. Manufactured from corrosion-resistant stainless steel (typically grades 304 or 316), these washers provide excellent durability, making them ideal for marine, industrial, structural, and outdoor applications.
These washers are available in a variety of outer diameter (OD) options to meet different performance requirements. Larger OD washers spread the load over a wider area, making them suitable for softer materials like timber or composite, while standard and smaller OD washers are ideal for compact spaces or general fastening.
Key Features:
Suited for 1 1/4" imperial bolts and threaded fasteners
Made from high-grade stainless steel for excellent rust and corrosion resistance
Helps prevent fastener pull-through, surface deformation, and joint loosening
Available in multiple outer diameters to suit specific substrate and load conditions
Suitable for marine, construction, heavy industry, and general-purpose fastening
Outer Diameter Options May Include:
Standard OD for everyday fastening tasks
Large OD for increased load distribution on softer or fragile materials
Compact OD for space-constrained assemblies or lighter-duty applications
1 1/4" stainless steel flat round washers with various outer diameters offer a dependable and versatile solution for heavy-duty and precision fastening across a wide range of environments.
