TIGHTU manufactures and supplies standard and custom fasteners for industrial buyers. Our work begins with the part itself—its dimensions, thread, material, applicable standard, assembly conditions, and intended use.
Based in Nantong, Jiangsu, China, TIGHTU supports the sourcing of fastening components for machinery, automotive parts, construction, electrical equipment, industrial manufacturing, and general assembly.
The product portfolio extends from commonly specified screws, bolts, nuts, and washers to threaded rods, studs, pins, rivets, threaded inserts, micro fasteners, and specialty components. Buyers can source standard parts or begin a custom project using a drawing, physical sample, material requirement, or application description.
This combination of product categories and specification routes helps procurement teams compare suitable options without treating every requirement as the same type of fastener.
Procurement teams often face hidden risks when sourcing industrial fasteners. Recognizing these challenges is the first step to building a reliable supply chain.
Substandard alloys or incorrect carbon content can lead to catastrophic failure under load or premature corrosion in harsh environments.
Poorly machined threads cause assembly delays, cross-threading, and compromised joint integrity, increasing overall production costs.
Supply chain bottlenecks and poor factory communication result in missed deadlines, halting your assembly lines and delaying critical projects.
With over 20 years of factory experience, we provide stability, precision, and certified quality for every order, whether standard or custom.
Deep manufacturing expertise ensures efficient production and technical problem-solving for complex orders.
From blueprint to final product, we manufacture custom fasteners tailored to your exact specifications.
Strict adherence to international certifications guarantees safety, reliability, and global compliance.
TIGHTU organizes its product range around the way components are specified and used in an assembly.
Screws, bolts, nuts, threaded rods, and studs for fastening, clamping, mounting, and structural connection requirements.
Washers, pins, and rivets used for load distribution, positioning, retention, alignment, or permanent joining.
Wire thread inserts, key-locking inserts, self-tapping inserts, and heat-set inserts for creating durable internal threads in different base materials.
Micro fasteners, captive fasteners, nylon-tip components, and non-standard parts developed around defined dimensions or application requirements.
Fastener selection depends on more than size. Material behavior, thread form, strength requirements, corrosion exposure, installation method, and the mating components can all influence the final specification.
Available material categories include carbon steel, stainless steel, alloy steel, copper, brass, aluminum, nylon, and titanium. The appropriate choice should be reviewed against the operating environment and performance requirement.
Standard parts can be specified according to relevant DIN, ISO, and ANSI product requirements. Buyers should identify the complete standard reference, dimensions, grade, and finish where applicable.
Custom fasteners can be reviewed from technical drawings, physical samples, material requirements, or application information. Clear specifications help define the part before sampling or production begins.
Our heavy industrial manufacturing process combines traditional forging strength with modern CNC precision to deliver high-performance fasteners.
Raw wire is cut and struck in high-pressure dies to form the fastener head and basic body shape, ensuring optimal grain flow and strength.
Threads are cold-rolled onto the shank for superior fatigue resistance, while precision CNC machining handles complex custom profiles.
Fasteners undergo controlled quenching and tempering to achieve the exact hardness, tensile strength, and durability required by the standard.
Anti-corrosion coatings like zinc plating, hot-dip galvanizing, or black oxide are applied to protect the fastener in its specific operating environment.
Take a look at our state-of-the-art facilities where raw materials are transformed into precision industrial fasteners.
We believe that a fastener is only as good as the testing behind it. Our QC lab ensures every batch meets your specified standard before it leaves our facility.
Spectrometer analysis confirms the chemical composition and grade of incoming steel, stainless, or alloy wire.
Using optical comparators, micrometers, and thread gauges to monitor tolerances during heading and rolling.
Tensile testing, yield strength verification, and hardness testing ensure structural integrity.
Salt spray tests for coating thickness and final visual inspections. Full material test reports (MTRs) are provided upon request.
A useful inquiry gives both sides a common technical basis. TIGHTU uses the available product and application information to determine whether the requirement is best addressed with a standard item or a custom manufacturing route.
Confirm the fastener type, dimensions, thread, material, finish, quantity, packaging, and intended application.
Review the cited product standard, drawing, sample, or other technical information used to define the part.
Manufacture the confirmed item and inspect the relevant dimensions and product characteristics against the agreed specification.
Prepare the finished fasteners according to the confirmed order and packaging requirements before shipment.
Share your drawing, sample information, target standard, preferred material, quantity, and application. These details give our team a practical starting point for reviewing your requirement.
