Nord-Lock Large O.D. Washer UNC - 316L Stainless Steel | AIMS

The Nord-Lock Large O.D. Washer UNC 316L Stainless Steel combines the preload retention of Nord-Lock wedge-locking with an enlarged bearing surface for soft substrates, oversized holes and surfaces requiring distributed clamping load in corrosive environments.

Marine and Offshore

• Deck hardware and railing fastening using UNC bolts on marine substrates with oversized or elongated holes
• Offshore structural connections on corroded or uneven surfaces needing a large bearing face alongside locking
• Aquaculture and coastal infrastructure fastening on FRP and GRP panels

Chemical and Industrial Processing

• Rubber and HDPE liner attachment on processing vessels requiring distributed clamping load
• Chemical plant pipe rack and equipment fastening on painted or coated surfaces
• Gasket and soft-face joint fastening requiring both load spreading and vibration resistance

Construction and Civil Engineering

• UNC-threaded structural connections into soft base materials or through oversized holes
• Cladding and facade fastening on coastal or corrosive structures
• Bridge, walkway and platform bolting requiring large-diameter washers in stainless assemblies

Food and Beverage Processing

• Panel and cladding attachment in wash-down environments using UNC fasteners
• Equipment bases and frames where stainless locking washers with large bearing faces are specified
