Hot dipped galvanised fastenings are widely used where strength, durability and long term corrosion protection are essential. At Duchy Fasteners, a comprehensive range of hot dipped galvanised fixings is held in stock, including high tensile grades to support demanding construction, engineering and infrastructure projects.


Available for purchase from the trade counter in Scorrier or online with UK wide courier delivery, galvanised fastenings from Duchy Fasteners provide a reliable solution for outdoor and exposed environments where unprotected steel would quickly deteriorate.

What Are Hot Dipped Galvanised Fastenings?

Hot dipped galvanised fastenings are carbon steel fixings that have been coated in molten zinc. This process creates a thick, durable zinc layer that fully coats the fastener, including threads and recesses, providing superior corrosion protection compared to other surface coatings.


The zinc coating acts as a sacrificial barrier, meaning it corrodes in preference to the steel beneath. This significantly extends the service life of the fastener, particularly in outdoor, industrial and rural environments where moisture and weather exposure are unavoidable.


Hot dip galvanising is widely recognised as one of the most effective methods of protecting steel fasteners against rust.

Galvanised Fastenings Held in Stock

Duchy Fasteners stocks a strong and practical range of hot dipped galvanised fastenings suitable for both general use and high load applications.


The galvanised range includes:

  • Hot dipped galvanised bolts in multiple sizes

  • Hot dipped galvanised nuts to suit matching threads

  • Hot dipped galvanised washers for load distribution and surface protection

These fixings are available in high tensile grades 8.8, 10.9 and 12.9, allowing customers to specify galvanised fasteners that meet both corrosion resistance and strength requirements.

High Tensile Galvanised Fasteners Explained

High tensile galvanised fastenings are used where structural strength and load bearing performance are critical. Duchy Fasteners stocks hot dipped galvanised fasteners in the following grades:


High tensile 8.8 fastenings are commonly used in construction and general structural applications where dependable strength is required.


High tensile 10.9 fastenings provide increased tensile strength and are often specified for heavy engineering, machinery and demanding assemblies.


High tensile 12.9 fastenings offer the highest strength level in this range and are suitable for applications where maximum performance is essential.


Combining high tensile steel with hot dip galvanising ensures these fasteners perform reliably in both mechanical and environmental terms.

Typical Uses for Galvanised High Tensile Fastenings

Hot dipped galvanised high tensile fastenings are commonly specified for:


  • Structural steelwork

  • Outdoor construction and civil engineering

  • Agricultural buildings and installations

  • Fencing, barriers and infrastructure

  • Industrial and heavy duty assemblies

These environments demand both corrosion resistance and mechanical strength, making galvanised high tensile fastenings a practical and cost effective choice.

Corrosion Resistance and Outdoor Performance

The thick zinc coating applied during hot dip galvanising provides excellent protection against rust in exposed environments. This makes galvanised fastenings well suited to outdoor use, rural locations and general construction settings.


While stainless steel may be preferred in coastal or marine environments, hot dipped galvanised fastenings offer outstanding performance in most outdoor applications at a more accessible cost point.


Correct specification ensures long service life with minimal maintenance.

Strength and Reliability

The use of high tensile grades ensures galvanised fastenings maintain structural integrity under load. When combined with the protective zinc coating, these fasteners offer a dependable balance of strength, durability and resistance to environmental wear.


Careful selection of grade and size is essential to ensure safety and compliance with project requirements, particularly in load bearing applications.
