Black Stainless Steel Fasteners
Our black stainless steel fasteners combine corrosion resistance with aesthetic appeal through the CB10 chemical blacking process. These precision-engineered components maintain dimensional stability while offering enhanced durability for industrial applications. Available in various grades including A2 (304) and A4 (316) stainless steel, they suit demanding environments from marine to aerospace sectors.
CB10 Coated Components
The CB10 coating process creates a non-reflective, corrosion-resistant finish on stainless steel fasteners. This four-stage treatment preserves dimensional accuracy while extending component lifespan. Ideal for applications requiring low reflectivity and improved lubrication properties, the coating benefits sectors like medical equipment manufacturing and architectural hardware production.
Marine Grade Fixings
Specialist marine-grade fasteners provide exceptional resistance to saltwater corrosion. Manufactured to exacting standards, these components include A4 (316) stainless steel variants with enhanced durability in harsh environments. Applications range from boat construction to coastal infrastructure projects requiring long-term performance under challenging conditions.
Precision Manufacturing
Our in-house manufacturing facility produces custom fasteners using advanced machinery including Star SR-32J sliding head lathes. This capability enables production of complex geometries with tight tolerances, supporting bespoke requirements across multiple industries while maintaining strict quality control throughout the manufacturing process.
Next Day Delivery
Orders placed before 1:30 PM are dispatched the same day, with standard next-day delivery across the UK. Free tracked delivery applies to orders over 50, combining rapid fulfillment with reliable shipment tracking to ensure timely component availability for both trade and private customers.
