Choosing screws for basic DIY jobs

Start with the job

How to think about length, head type, material and the surface being fixed. Before choosing a method, look at the material, the environment and what would happen if the fix failed.

Practical checks

• Wall type decides which plug or anchor is suitable.
• Pilot holes reduce splitting but must be the right size.
• Heavy items need proper assessment, not guessed load ratings.
• Keep the work visible and easy to inspect.
• Treat uncertain or safety-critical work as a reason to stop and seek better guidance.

Good habits

Work slowly, test on scrap or a hidden area where possible, and stop if the material starts to crack, crush, mark or move unexpectedly.

Safety note

Check for hidden cables and pipes before drilling. Wall fixings depend on wall type and load. Do not invent load ratings. Heavy items need appropriate fixings, judgement and eye protection when drilling.
