Client Testimonials

  • Beyond Standard Fasteners – Precision Where It Counts
    While nuts and bolts are often seen as simple commodities, the more technical, bespoke components are where Victory truly stands out. Their products are specialised, offering unique solutions that go beyond standard fasteners. I source carbon steel hex bolts, high-grade 10.9 and 12.9 bolts, as well as F436 washers and various nuts—always tailored to the application. When it comes to high-grade bolts, Victory is my first and only choice.

  • Competitive Pricing, Unmatched Speed & Reliability
    Victory competes with overseas suppliers on price, but when it comes to speed, accuracy, and reliability, they’re unmatched—especially when they have stock available.

Just last week, when another supplier let us down, Victory stepped in immediately, ensuring we had what we needed without delay.

  • Meticulous record-keeping and excellent traceability
    We receive Certificates of Conformity from Victory, and while they offer higher-level certification, it’s not something we require. We know they source from both Europe, but for us, the origin isn’t a concern—what matters is the quality. On one occasion, a product didn’t meet the customer’s specification, but thanks to Victory’s meticulous record-keeping and excellent traceability, we quickly identified that the issue was on the customer’s end, not Victory’s. Their attention to detail is invaluable

  • Quick Responses and Specialist Expertise Make a Difference
    I moved to Hayley about 5 years ago and reconnected with Mike. Our business with Victory has gone from strength to strength from a standing start. Their expertise and USP is in the specials any screws or bolts that require drilling, cutting, or plating. They are so quick t o react I have countless examples of them turning around enquiries in days.
