Ultra Thin Flat Washer — SS 304 What it is Ultra thin flat washer made from stainless steel 304. Sold in packs of 10, 20, or 50 pieces. Specification format: Inner Diameter × Outer Diameter × Thickness (use this format when selecting the correct size). Key benefits Lowprofile design: very thin thickness keeps assemblies compact and prevents interference in tight spaces. Load distribution: spreads clamping force over a larger area to protect surfaces and reduce fastener pullthrough. Corrosionresistant and durable: SS 304 construction resists rust and performs well in common indoor and outdoor environments, extending service life. Consistent, reliable fit: manufactured to maintain a uniform thickness and flatness for predictable performance in precision assemblies. Function and compatibility Functions as a spacer, loadbearing surface, and protective barrier between fastener head/nut and mating surface. Compatible with bolts, screws, studs, and threaded rods when Inner Diameter matches the fastener shank. Select size by matching the Inner Diameter to your fastener and using the Outer Diameter and Thickness to confirm clearance and load distribution needs. Performance attributes Material: Stainless Steel 304 — corrosion resistance, strength for generalpurpose applications. Ultrathin profile: ideal where minimal stack height is required. Available quantities: choose 10, 20, or 50 pieces to match small projects or larger assembly runs. Typical applications Electronics and instrumentation: hold PCBs or components in place without adding noticeable height, or use as lowprofile spacers between panels. Automotive and vehicle trim: secure interior panels, trim, or brackets where clearance is limited and corrosion resistance is desired. Appliances and light machinery: protect finished surfaces and distribute load under fastener heads in compact assemblies. How to choose the correct washer Measure the fastener shank diameter and select a washer with an Inner Diameter slightly larger than the shank. Confirm the Outer Diameter provides adequate bearing area for load distribution. Verify the Thickness meets your clearance and stacking requirements; use the specification format Inner Diameter × Outer Diameter × Thickness when ordering. Pack options Available in quantities of 10, 20, or 50 pieces to suit repairs, prototypes, or production use. using the specification Inner Diameter × Outer Diameter × Thickness and select SS 304 material with the desired pack quantity (10 / 20 / 50 pcs).
