Guangdong Pinshang Hardware Products Co., Ltd. — PremFixer is a specialized manufacturer integrating R&D, production, and global sales of bicycle and motorcycle fasteners. Based in Shaoguan, Guangdong, we focus exclusively on full-category fastening solutions for bicycles, e-bikes, and lightweight motorcycles — from frame chassis bolts to drivetrain hardware, brake mount kits, and custom OEM components.
Who We Are
A specialized fastener factory built for the bicycle industry
We are not a general hardware supplier that happens to sell bolts. PremFixer was founded with a single focus: provide bicycle and motorcycle manufacturers with fasteners that meet the same engineering standards they demand from frame materials, bearings, and drivetrain components.
Our engineering and production team brings decades of combined experience in bicycle and motorcycle fastener applications. We understand the difference between a bolt that fits and a bolt that works — through vibration, weather, thermal cycling, and years of service. From a single M5 bottle-cage screw to a complete model-year fastener BOM for a production frame, we treat every order as an engineering commitment, not a transaction.
We invest in the documentation, certifications, and process control that professional buyers and engineers require: EN 10204 3.1 material certificates, ISO 9227 salt spray reports, RoHS & REACH declarations, and full batch traceability. Because we know that when your brand ships a bicycle, our fasteners are part of your reputation.
Mission, Vision & Values
What drives us every day
Mission
Deliver precision fasteners that combine Asian manufacturing efficiency with international quality standards — making professional-grade fasteners accessible to bicycle manufacturers of every scale, from boutique frame builders to mass-production assembly lines.
Vision
Become the default fastener engineering partner for the global bicycle industry — the supplier that product designers, sourcing managers, and quality engineers turn to first when they need bolts that won’t fail.
