Not sure which finish to choose?

We stock fasteners in three finishes to suit every application. BZP is ideal for indoor and sheltered use. HDG gives heavy-duty protection for outdoor, structural, and timber work. A4 Grade 316 Stainless is the right choice for marine, coastal, and chemical environments. Read our guide to pick the right finish for your project.
