Expert Turning & Machining Capabilities

Turning, boring, grinding, and fastener production all in one place.

Our services cover everything from simple turning to full machining jobs. We create smooth shafts, tight tapers, and complex profiles with reliable accuracy. We also produce custom fasteners and fittings that match your design requirements. Need boring, drilling, or grinding? We do that too. From thread-ready bolts to tight-tolerance parts, we deliver components that work right the first time. With every job, we focus on function, fit, and durability. Our custom threading & turning services are built to support industries that can’t afford to fail.

Specializing in:

Threading Services We Offer

Precision threading for every application and industry need.

We handle all types of threading projects with close attention to detail. Whether you need strong seals, smooth fits, or custom threads, we’ve got you covered.

Internal (ID) Threading

Ideal for components like couplings and fittings that require precise internal grooves.

External (OD) Threading

Used for bolts, fasteners, or any part needing accurate outer threads.

Metric & Standard Threads

We support both metric and imperial systems for full compatibility.

Tapered Threading

Perfect for pressure-sealing parts such as NPT threads.

ACME & Square Threads

These are used in motion systems needing strong, wide threads.

Custom Thread Profiles

Built to match your exact needs, down to every last detail.

Advanced Gear & Spline Machining

Precise ID/OD profiles for gear-driven and power systems.

Gear and spline profiles are critical for motion systems. We create internal and external spline features with tight tolerances and repeatable quality. Whether you’re replacing a worn part or building new equipment, we match original specs or help you redesign better ones. These components must mesh perfectly—and we make sure they do. We use proven techniques to cut gear teeth, splines, and grooves in all sorts of materials. It’s all about making the connection smooth, efficient, and long-lasting. Our custom threading & turning services extend to profiles that require focus and finesse.

Component Rework & Alloy Welding

Old parts don’t always need replacing—they just need the right repair.
Our rework services restore worn or outdated components to usable condition.
We rebuild dimensions, fix thread damage, and correct wear.
Need welding? We work with most alloys to join or reinforce key areas without affecting performance.
From minor fixes to full restoration, we treat every part like it matters.
Our shop is equipped to handle precision welding and machine rework in one place.
When timelines are tight and budgets matter, fixing an existing part is often the smartest move.

Frequently Asked Questions

What are custom threading & turning services?

Custom threading & turning services involve shaping and cutting threads on metal parts, along with forming smooth cylindrical surfaces. These services are used to create components that fit precisely in mechanical systems.

What is the difference between ID and OD threading?

ID threading refers to internal threads cut inside a hole, like in fittings or couplings. OD threading means external threads cut on the outer surface, such as on bolts or shafts.

Can I request metric or standard threads?

Yes, we machine both metric and standard thread profiles to match your system requirements, ensuring perfect fit and compatibility.

What are ACME and square threads used for?

ACME and square threads are typically used in power transmission applications where strength and smooth motion are essential, such as in lead screws.

What is the purpose of tapered threading?

Tapered threading is designed for sealing applications. It creates a tight fit that prevents leaks, often used in pressure systems and pipe connections.
