Lex Hardware Custom Springs
Compression Springs
When a force pushes against the ends of the spring, the coils move closer together.
Extension Springs
It stretches when a pulling force is applied and returns to its original length when the force is removed.
Torsion Springs
stores energy as its legs twist around the axis and releases it as rotational force.
Die Springs
Heavy-duty springs designed to withstand high loads and repeated use in tooling and die applications.
Battery Springs
Small compression springs used in battery holders to maintain electrical contact and absorb vibration.
Compression Springs
A circular spring applies uniform inward or outward tension to hold components securely in place.
Wave Springs
A wave-like shape provide the same force as traditional compression springs in less space.
Disc Springs
Keep components spaced and maintain tension on shafts, under bolt heads, and at valve ends.
Rotor Springs
Stores and releases energy through rotational twisting.
Gas Springs
Use compressed gas to provide controlled force and motion.
Plastic Composite Springs
The lightweight, corrosion-resistant springs made from reinforced polymers that store and release energy like metal springs.
Linear Wave Springs
Provide axial force in a compact, space-saving design using waves in a flat wire coil.

CNC Machining FAQs
What's music wire?
Music wire is a high-carbon steel wire with excellent strength and elasticity, commonly used to make precision springs. It offers great fatigue resistance at room temperature but has limited corrosion and heat resistance.
Can you make springs from alloy wire?
We sure can! Alloy wire provides higher strength, better fatigue life, and improved heat and corrosion resistance compared to carbon steel, making it ideal for springs used in demanding or high-stress applications.
What types of materials can be used to manufacture springs?
We use the best metal for your project. We form standard springs and specialty springs made from stainless steel, copper wire, galvanized wire, Inconel, steel alloys, and more.
What industries do you serve?
CWe make springs for just about any industry you can think of. We’ve made springs for fast food automation and leading restaurant equipment suppliers. We’ve manufactured heavy-duty springs for residential and industrial garage doors and commercial overhead doors. We produce springs for attic ladders. We’ve put the spring in many a trampoline. We’ve made high-tensile springs for the agricultural industry.
Do you make springs from rectangular wire, square wire, or flattened round wire?
Yes, we do!
What is tensile strength?
Tensile strength is the maximum stress a material can withstand when being pulled or stretched before it breaks.
