Double stainless steel thread, M8, L60, AISI304

The Strofix double stainless-steel thread M8 L60 is an AISI 304 double-end threaded stud (hanger bolt) with an M8 machine thread and 60 mm length. One end has a coarse wood screw thread for screwing into timber; the other end has an M8 metric machine thread for receiving a nut. Intended for wooden frame building and timber substrate installations.

The double-end stud bridges wood-to-metal connections in railing installations. The wood screw end is driven into a timber deck, beam, or frame member, and the protruding M8 machine thread end receives a nut and washer to secure a railing post base plate or other metal component. The M8 thread matches base plates with Ø8.5–9 mm bolt holes, such as the compact Ø80 mm round tube base plate and the 80 × 80 mm square tube base plates. AISI 304 stainless steel provides corrosion resistance at the wood-metal interface.

This SKU is a single fixed configuration – M8, L = 60 mm, AISI 304 only.

Use cases:

• Anchoring railing post base plates to wooden decks and terraces with M8 pattern
• Railing installations on timber-framed balconies and mezzanines
• Securing M8-pattern base plates to wooden beams and structural timber
• Wood-to-metal bridging for railing fixings on wood substrates
• Timber frame building railing installations where concrete anchoring is not applicable

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.
