Washer, M8, AISI304

The Strofix washer M8 is an AISI 304 stainless-steel flat washer for M8 bolts, screws, and anchor rods. The washer is 1.6 mm thick (DIN 125). Supplied with a satin finish.

The flat washer is placed between the nut (or bolt head) and the surface being fastened. It distributes the clamping force over a larger area, prevents the nut from digging into softer materials, and provides a smooth bearing surface for consistent tightening. In railing installations, the washer is used under nuts on M8 anchor rods, under bolt heads on M8-pattern base plate assemblies, and in any M8 bolted connection where load distribution is required. AISI 304 stainless steel matches the grade used on the Strofix M8 screws, double-thread studs, and other M8 fasteners.

This SKU is a single fixed configuration – M8, AISI 304 only.

Use cases:

• Under nuts or bolt heads on M8 anchor rod assemblies
• Under M8 bolt heads in base plate and glass clamp assemblies
• Load distribution on any M8 bolted connection in railing systems
• Preventing surface damage from nut or bolt head bearing on stainless-steel components
• General M8 fastening hardware in architectural stainless-steel installations

About Anchors & Screws

Anchors and screws fix glass adaptors, French balcony holders, brackets, railing posts and other hardware to the building – to concrete, masonry, insulated façades or timber.

The range covers S235 steel anchor rods (Ø16 mm with an internal M8 and Ø20 mm with an internal M10 thread, 220–400 mm) for chemical anchoring, a zinc-plated anchor sleeve M10 × 80 mm, a PVC spacer sleeve for fixings through insulation, AISI 304 threaded rods and studs (M10 × 200 threaded rod, M10 × 50 set screw, M8 × 60 and M10 × 100 double threads for timber), DIN 912 screws, DIN 917 cup nuts, flat washers, and wood screws Ø8 and Ø10 mm in AISI 316 or coated carbon steel in RAL colours.

The right fastener depends on the substrate, the façade build-up, the thread size of the fitting and the load.
