Boca Raton, FL 33431, United States, 13th Nov 2026 – Yijin Solution, an experienced precision manufacturer, has announced custom fastener manufacturing as part of its service range. The offer sits alongside the company’s CNC machining work. According to the company, orders carry no minimum quantity.
Yijin Solution makes bolts, nuts and other threaded parts to customer drawings at a 12,000-square-meter facility in Shenzhen. Automotive, aerospace, medical, new energy, semiconductor and robotics are among the industries the company serves with fasteners, along with mold making and defense.
What Is New: Two Routes to a Finished Fastener
Fasteners are made by cold heading and by CNC and Swiss-type turning, the company said. Cold heading forms metal into shape in several stages without cutting material away. It suits large runs of small, uniform parts. Yijin Solution operates 150 cold heading machines. Runs can range from 10,000 to more than 1,000,000 pieces.
CNC turning and Swiss-type machining cut parts from bar stock. They suit smaller runs and parts with more complex shapes. The company runs more than 110 Swiss-type lathes, with precision tolerances starting at ±0.02 mm. For buyers choosing between routes, the split follows run size and part shape. Volume work goes to cold heading, and precision or complex parts go to turning.
“Fastener buyers often need one process for volume and another for precision,” said Gavin Yi, CEO of Yijin Solution. “Sourcing both from Yijin Solution keeps specifications in one place. Offering fasteners alongside the company’s CNC range follows that logic.”
Threads are formed by rolling or by tapping. Thread rolling is offered across a wide range of metric sizes, and tapped holes are checked with go/no-go gauges. The company also describes custom thread forms such as ACME and buttress as available through CNC turning.
Materials, Treatment and Finishes
Yijin Solution works with carbon and alloy steel, stainless steel, brass, aluminum, titanium and nickel alloys. Materials come with mill certification and batch or heat lot traceability, according to the company. Strength grades follow both SAE and ISO systems.
Heat treatment is carried out in-house, covering quenching, tempering, carburizing and induction hardening, and hardness is tested for each batch. Finishing options include zinc plating, hot-dip galvanizing, black oxide and zinc flake coatings, with passivation for stainless steel. Salt spray test reports are supplied with orders where applicable, and plating and passivation work is listed against recognized ASTM, ISO and AMS standards.
Inspection, Lead Times and Ordering
Batch checks on the fastener line use thread gauges, hardness testers, optical comparators and tensile testers. Dimensional inspection reports, material certificates and plating test results can accompany an order. The company said it holds 137 inspection instruments across its operations.
Lead times run from 7 to 15 days for samples and from 10 to 20 days for production runs. Expedited shipping is available for time-sensitive orders.
Prototype runs can be as small as 10 pieces, which suits buyers who want to start with a small batch.
Customers upload drawings through an online quoting platform, and the company states that a quote is returned within 24 hours. Fastener work is easier to review when a drawing states the thread class, strength grade, material and finish together. Yijin Solution has published fastener guides for buyers comparing suppliers in China.
Looking Ahead
Yijin Solution expects fastener requests to arrive in different materials, grades and quantities. It plans to match each one to a cold heading or turning route before production starts. Reviewing each drawing first is how the company intends to handle that range of requests.
“Each fastener drawing will continue to be reviewed for its material, thread and finish before a process is chosen,” said Yi. “The aim is to keep the quoting and inspection steps the same as order sizes change, from a prototype run to a large production order.”
