Frequently Asked Questions
What types of industrial fasteners are included in this category?
Our fasteners range covers structural bolts, heavy hex nuts, flat and spring washers, socket head cap screws, threaded rods, rivets, self-tapping screws, and specialized railway track fixings engineered for high-vibration and load-bearing applications.
What materials and surface finishes are available for corrosion protection?
We offer fasteners in high-tensile carbon steel, A2/A4 stainless steel, and brass. Protective surface coatings include hot-dip galvanized (HDG), zinc-plated, sherardized, and specialized multi-layer anti-corrosion finishes built to endure harsh outdoor and coastal environments.
Are Unipart’s fasteners compliant with ISO, DIN, and railway specifications?
Yes. All our fasteners meet stringent international manufacturing standards (such as ISO, DIN, and BS) and relevant rail network approvals (including Network Rail PADS where specified) to guarantee thread precision, shear performance, and structural integrity.
Do you offer vibration-resistant locking solutions for heavy machinery and rail tracks?
Absolutely. We supply self-locking nuts (e.g., Nylon-insert/Nyloc and prevailing torque lock nuts), wedge-locking washers, and specialized vibration-proof hardware designed to prevent loosening caused by heavy mechanical shock and continuous rail traffic.
Can I procure fasteners in bulk quantities or custom thread/length specifications?
Yes. We support full bulk commercial purchasing for large construction, infrastructure, and manufacturing operations. For non-standard dimensions, custom coatings, or bulk volume quotes, please reach out directly to our technical sales team.
