Nuts are one of the most essential components in mechanical fastening systems. As a critical threaded fastener, a nut works together with bolts, screws, and threaded studs to create a secure and removable connection between mechanical components.
From standard Hex Nuts to advanced Lock Nuts, Self-Locking Nuts, Flange Nuts, Weld Nuts, Copper Nuts, and Custom Precision Nuts, selecting the correct nut type is essential for ensuring mechanical strength, vibration resistance, corrosion protection, and long-term reliability.
JUXIN FASTENERS is a professional Nut Manufacturer and Custom Fastener Supplier, providing high-quality industrial nuts for global OEM customers in automotive, machinery, electronics, construction, renewable energy, medical equipment, and industrial manufacturing industries.
We manufacture Metric Nuts, Inch Nuts, Stainless Steel Nuts, Carbon Steel Nuts, Brass Nuts, Copper Inserts, and Custom OEM Nuts according to international standards and customer specifications.


A nut is a threaded mechanical fastener with an internal thread designed to work with a matching bolt or screw.
The internal thread allows the nut and bolt to create a clamping force, securely joining two or more components together.
For example:
M4 × 0.7 nut matches an M4 × 0.7 screw
1/4"-20 nut matches a 1/4"-20 screw
Correct thread matching is essential to ensure:
Proper installation
Reliable fastening
Load capacity
Long service life
