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 20+ years of core team experience means 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.
Values
