Product details

Our factory specializes in manufacturing high-performance stainless steel Bolt and matching Nut series, among which cross recessed hex flange bolt is one of our core wholesale fastener products. This integrated flange bolt combines hex head, cross drive and serrated anti-slip flange washer as one piece, eliminating extra gasket installation steps for assembly clients. All raw materials adopt food-grade and marine-grade stainless steel to guarantee long-term anti-rust performance for outdoor and humid working environments. As direct factory supplier, we support bulk wholesale for global fastener importors, machinery distributors and retail chain merchants. The Bolt can be produced per DIN, ISO international standards, and we provide full OEM & private label customization service to meet brand merchants’ personalized procurement demands. Compared with ordinary hex bolts, the serrated flange base enhances friction locking force to prevent loose connection under vibration working conditions, widely matched with our supporting stainless steel Nut for complete fastening assembly solutions.

4.. Product Details

Raw Material Selection

All our hex flange Bolt products use certified 304 or 316 stainless steel bars sourced from qualified domestic metal mills. 304 stainless steel Bolt fits general indoor machinery and construction use with balanced cost and anti-rust performance, while 316 stainless steel flange Bolt provides superior acid and salt corrosion resistance for coastal, marine and food processing equipment installation.

Manufacturing Craft

The whole production flow of each Bolt includes metal blank cutting, hot forging hex flange head forming, precision thread rolling, surface passivation treatment and full finished product sorting. Thread rolling technology ensures complete, uniform thread teeth without burrs, avoiding thread slipping during repeated disassembly. The integrated flange and hex head are forged in one molding process, eliminating separation risk under long-term vibration working conditions. After forming, all Bolt workpieces go through chemical passivation to form a dense anti-rust protective film on metal surface, meeting export hardware quality standards with no paint or wax coating to prevent chemical residue contamination.

Core Competitive Advantages for Wholesale Buyers

Compared with split bolt and washer combinations, our integrated hex flange Bolt cuts installation labor cost by over 30% for large construction and equipment assembly projects. Consistent dimensional tolerance across all bulk production batches reduces product return rate for overseas distributors. Our factory maintains stable raw material stock to guarantee on-time delivery for large container wholesale orders, avoiding supply chain delays for import merchants.

Strict Quality Control System

Every production batch of flange Bolt undergoes multi-stage inspection: raw metal composition testing, head hardness tensile testing, thread size caliper inspection, salt spray anti-corrosion testing and finished appearance sorting. Unqualified Bolt pieces are fully separated and recycled, only qualified products enter export packaging links to protect wholesale clients’ brand reputation in local markets.
