Steel anchor D16, L 320mm, M8

The Strofix steel anchor D16, L 320 mm, M8 is an S235 galvanized carbon steel anchor rod with a 320 mm length, M8 thread, and 16 mm body diameter (ø). The material is S235 structural steel with a galvanized coating.

The 320 mm length provides standard-depth embedment for floor slab and balcony slab installations. 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 / 105 × 105 mm square tube base plates. This is the longest M8-threaded S235 anchor in the Strofix range, providing maximum embedment for M8 bolt pattern applications. The anchor rod is embedded into concrete either chemically using anchor mortar or cast into wet concrete, with the M8 threaded end protruding to secure the structural component. S235 galvanized steel provides corrosion protection for standard interior and protected exterior applications.

This SKU is a single fixed configuration — M8, Ø16, L = 320 mm, S235 galvanized only.

Use cases:

• Standard-depth M8 concrete anchoring of railing post base plates
• Longest M8 anchor for maximum embedment with M8-pattern base plates
• Glass canopy bracket anchoring where base plates use M8 bolt holes
• Floor slab and balcony slab installations requiring 320 mm embedment with M8 thread
• Chemical or cast-in anchoring for M8-pattern structural fixings

FAQ:

What are the anchor rod dimensions?

The rod has an M8 thread, 16 mm body diameter (ø), and 320 mm total length (L).

How does this fit in the M8 anchor rod range?

The Strofix M8 S235 anchor range includes two lengths: 220 mm and this 320 mm. The 320 mm provides deeper embedment for standard floor slab installations. For M10 thread, the range extends to 150, 220, 320, and 400 mm lengths.

What base plates use M8 bolt holes?

What material is used?

S235 structural steel with galvanized coating. For stainless-steel anchors, see the AISI 304 anchor (L = 330 mm) in the Strofix range.

How is the anchor installed?

The anchor can be chemically bonded using anchor mortar (Essve ONE or ONE-ICE) or cast directly into wet concrete.

What is the body diameter?

The anchor body is 16 mm (ø = 16 mm).

About Anchors & Screws

Anchors and screws are the mechanical fasteners that secure glass adaptors, canopy brackets, railing posts, French balcony holders and other architectural hardware to the building substrate. They transfer structural loads from the visible hardware into concrete, masonry, insulated façades or timber frames.

Strofix supplies 16 products in this category: steel anchors in four lengths (150, 220, 320 and 400 mm) with rod diameters of Ø16 and Ø20 mm, an anchor sleeve (M10 × 80 mm), a spacer tube (L = 100 mm), individual screws (M10 × 45), cup nuts (M10), washers, double stainless-steel threads (M8, 60 and 100 mm), a wood screw (Ø10 × 180 mm), and pre-matched screw-and-fastener sets for 1, 2, 3 or 4 glass canopy brackets — configurable for masonry without insulation, masonry with insulation and timber-frame construction.

Materials are AISI 304 stainless steel and S235 structural steel.

The correct fastener depends on wall type, hardware product, bolt size and required embedment depth.
