What Are Fasteners? UK Guide for Yeovil & Somerset Buyers
Released On 30th Apr 2026
What are fasteners?
Fasteners are mechanical components used to securely join two or more materials together. Common examples include bolts, screws, nuts, and washers.
Types of fasteners
The main types of fasteners are:
- Bolts
- Screws
- Nuts
- Washers
- Anchors and fixings
Choosing the right fastener
To choose the correct fastener, consider:
- Material – stainless steel for corrosion resistance
- Size & thread type – metric vs imperial
- Load requirements – light vs heavy-duty
- Environment – indoor vs outdoor
Metric vs imperial fasteners
Metric fasteners (M sizes): Standard in modern UK construction
Imperial fasteners (UNC, UNF, BSW): Used in older machinery and vehicles
Many projects in Yeovil and across Somerset still require both systems, especially in engineering and maintenance work.
Best fasteners for outdoor use
The best fasteners for outdoor use are:
- Stainless steel (A2 or A4)
- Galvanised steel
These materials resist rust and corrosion in UK weather conditions.
