RS Pro Carbon Steel Anchor Bolt M20, fixing hole diameter 22mm, length 260mm

The 908‑6808 is a high‑strength anchor bolt engineered for critical fixings in concrete, masonry and structural steel installations. Manufactured from carbon steel and hot‑dip galvanised for corrosion protection, it features an M20 thread size, a total length of 260 mm and is designed to fit through a 22 mm diameter fixing hole. This heavy‑duty anchor stud is compatible with both injection resin and spin‑in glass capsule systems, making it a versatile solution for demanding construction, industrial and infrastructure applications.

Unique Features and Benefits of this Carbon Steel Anchor Bolt M20

• Carbon‑steel construction delivers superior tensile strength and durability in structural fixings.
• Hot‑dip galvanised finish (min ~42 µm coating) ensures enhanced corrosion resistance, even in challenging indoor/outdoor conditions.
• M20 thread size with 260 mm overall length accommodates deep embedment for strong anchoring in thick substrates.
• Designed for 22 mm fixing holes with a maximum fixing thickness of about 55 mm, simplifies installation and ensures secure clamping.
• Suitable for both chemical (resin) anchor systems and classic expansion anchor methods, providing flexibility in material or substrate conditions.

Optimised Performance for Structural Anchoring

Built to withstand dynamic loads and long‑term structural stress, the RS PRO 908‑6808 ensures firm anchorage even under vibration, load reversal or substrate shifts. The galvanised surface preserves the integrity of the anchor in corrosive or humid environments, which is crucial for installation near machinery, outdoor frames or chemical process equipment.

Applicable Areas of the Product

• Concrete and masonry anchor points for structural steel columns, frames or machine bases.
• Fixings for equipment foundations, heavy‑duty supports or anchor plates in industrial plants.
• Installation of outdoor structures: signage, handrails, containment systems.
• Resin‑anchored systems in brittle or irregular substrates.
• Retrofit anchoring in existing slab or wall installations using chemical capsule anchors.
• Infrastructure applications such as stairs, platforms, walkways and safety barriers in commercial/industrial sites.
