Fastener Manufacturing Capabilities
Ruinuo Fastener’s fastener manufacturing capabilities cover cold heading, hot forging, thread rolling, and export packaging, supporting stable bulk production for global distributors, importers, and industrial projects.
Our Fastener Manufacturing Process
From raw material preparation and forming to thread processing, inspection, and export packaging, each production stage is organized to support consistent quality, custom specifications, and reliable bulk supply.
01
Raw Material Preparation
Steel wire rod and bar materials are prepared according to product dimensions, strength requirements, and order specifications.
02
Cold Heading & Hot Forging
Cold heading supports efficient volume production, while hot forging is used for larger diameters and more demanding fastener geometries.
03
Thread Rolling & Machining
Threads and critical dimensions are formed or machined according to drawings, applicable standards, and order requirements.
04
Heat Treatment & Finishing
Heat treatment and surface finishing are arranged according to the required property class, corrosion protection, and application conditions.
05
Inspection & Verification
Dimensions, threads, appearance, and mechanical requirements are checked against order specifications before release.
06
Sorting & Export Packaging
Finished fasteners are sorted, labeled, and packed for bulk handling, container loading, and international delivery.
Fastener Production Equipment
Our production equipment supports cold heading, nut forming, thread rolling, and hot forging for stable production of standard and custom fasteners.
Cold Heading Production Line
Cold heading equipment forms steel wire rod into bolt blanks for efficient batch production of standard and custom fasteners.
Hex Nut Production Equipment
Hex nuts are produced in batches with consistent dimensions and internal threads for standard and custom order requirements.
Threaded Rod Rolling Equipment
Thread rolling equipment forms continuous external threads on steel rods for consistent profiles and stable batch production in standard and custom sizes.
Fastener Hot Forging Equipment
Hot forging equipment forms heated steel blanks for larger-diameter and custom fasteners with more demanding shapes and production requirements.
