从China供应商批量进口51mm, 1# Metal Book Paper Binder Clips

Yiwu Joinus Stationery Co., Ltd. produces 51mm, 1# metal book paper binder clips under item number AF-2064-1, sized for medium-duty document binding. The 51mm width corresponds to the 1# size classification common in Chinese stationery manufacturing, indicating nominal capacity to secure approximately 80-100 sheets of 80 gsm paper. The metal construction uses formed steel wire with black or coloured enamel finish, looped through pressed steel wire handles that provide clamping force through torsional spring action.

The steel wire gauge determines clamping pressure and fatigue resistance, though exact wire diameter and material grade are not stated. Typical binder clip wire ranges from 1.2mm to 1.6mm diameter for this size category, with Q195 or similar low-carbon steel being standard. The enamel coating provides corrosion resistance and colour options; standard finishes include black, silver, and assorted colours for retail assortments. The 51mm Gibbs & angle of the wire loops affects handle leverage and clamping distribution across the jaw length.

Buyers include office supply distributors, school stationery wholesalers, corporate procurement departments, and retail chains requiring bulk quantities of standard fastening products. The 12-piece box and 720-piece carton configuration suits wholesale distribution through traditional stationery channels. Import buyers should verify wire gauge and finish durability against their market regulations, assess whether nickel-free or RoHS-compliant formulations are required, and confirm that the 1# size designation aligns with their existing product lines or customer expectations.

Yiwu Joinus Stationery Co., Ltd. is located at 423# Suxi Road, Xufeng Cun, Suxi, Yiwu, Zhejiang Province, placing it within China's largest small-commodity distribution hub. The Harbor trust tier indicates basic verification without assessed trading performance. The zero percent response rate and zero average response hours mean no platform-mediated inquiry data exists, so buyers must rely on direct outreach for communication reliability assessment.

The company specialises in stationery products, with this binder clip representing a standard metal fastening item within a broader catalogue. No information is provided about factory square footage, workforce, annual output, machinery, or major accounts. The listed price of USD 0.046 per piece and 5-carton MOQ are specific data points that buyers can use for initial costing, though both require confirmation as binding quotations. Buyers should request company registration documents, factory audit capability, and reference samples before committing to volume orders.
