General FAQs
There are a lot of stamping companies, why should I buy from Freeway?

Freeway developed horizontal-stamping machines that minimizes tool cost and maximizes manufacturing efficiency. This reduces lead-time and saves you money.

Does Freeway have an extensive tooling inventory?

Freeway maintains over 10,000 washer tools. Many times, we can interchange tools which translates to a cost savings in your tooling budget.

What size are Freeway’s stamping presses?

We are able to stamp a wide array of products. We run presses that range from 10 to 400 tons.

What is the maximum thickness Freeway can stamp?

Our maximum thickness is .312 (7.92mm)

Can Freeway perform additional operations on my manufactured components?

Yes. Our specialized subsidiary, Triangle Machine, can take a wide variety of parts and complete secondary machining requirements. If more assembly is required, Freeway can attach components as an additional operation.

Can I show you my product design? Can you offer application engineering?

Yes. Our engineers can work with you throughout the whole process. From design inception through product manufacturing, Freeway’s engineers are here to help your product perform while saving you money.

Is Freeway financially stable?

Since 1944, Freeway has remained financially healthy. We are a financially conservative company maintaining a strong balance sheet.

What types of metal washers does Freeway Corporation manufacture?

Freeway Corporation manufactures a comprehensive range of precision metal washers, including structural washers, copper washers, brass washers, stainless steel washers, tooth washers, double chamfer washers, C-washers, and stamped metal washers. Each product is engineered to meet specific load-bearing, sealing, or locking requirements across industrial and commercial applications. With decades of stamping and machining expertise, Freeway Corp produces both standard and custom washer configurations to exact tolerances.

What are copper crush washers and what are they used for?

Copper crush washers (also called copper sealing washers) are soft, annealed copper rings designed to create a leak-proof seal when compressed between two mating surfaces. They are widely used in automotive, hydraulic, and fluid system applications — including oil drain plugs, brake line fittings, and fuel system connections — where a reliable, pressure-resistant seal is critical. When tightened, the copper deforms slightly (or “crushes”) to fill microscopic surface irregularities, eliminating fluid or gas leakage. Freeway Corporation’s copper crush products are available in a range of sizes and thicknesses for OEM and aftermarket needs.

What are structural washers and when are they required?

Structural washers are heavy-duty, hardened washers used in structural steel and construction applications to distribute the load of a bolted connection over a wider surface area. They are commonly required in steel beam connections, bridge construction, tower assembly, and high-load anchor bolt applications where standard washers would deform under pressure. Freeway Corporation manufactures structural washers to specifications including ASTM F436, ensuring compliance with construction and engineering standards. These washers are critical wherever bolt load integrity and joint stability are non-negotiable.

What is the difference between stamped washers and precision-machined washers?

Stamped washers are produced by pressing flat sheet metal through a die — a high-speed, cost-effective process best suited for high-volume, standard-tolerance applications such as general fastening, load distribution, and sealing. Precision-machined (CNC-turned) washers, on the other hand, are manufactured using computer-controlled cutting tools, enabling tighter tolerances, complex geometries, and superior surface finishes required in aerospace, automotive, and critical mechanical assemblies. Freeway Corporation offers both capabilities — stamped washers through its core manufacturing operations and precision-turned components through its Triangle Machine Products division — allowing customers to source both types from a single, vertically integrated supplier.

What materials are available for custom washer manufacturing?

Freeway Corporation produces custom washers in a wide variety of metals to match specific application requirements:

 

Copper – ideal for sealing/crush applications; excellent thermal and electrical conductivity

Brass – corrosion-resistant; commonly used in plumbing, electrical, and marine environments

Stainless Steel – high strength and corrosion resistance for harsh or sanitary environments

Carbon Steel – cost-effective for structural and high-load applications

Alloy Steel – hardened for heavy-duty structural and construction uses

Custom material selection is guided by the load requirements, environmental exposure, and industry standards of each application. Freeway’s engineering team works with customers to identify the optimal material for performance and cost efficiency.

What are tooth washers and when should you use them?

Tooth washers (also called toothed lock washers or serrated washers) are metal washers with sharp, serrated teeth along the inner or outer edge. When a fastener is tightened, the teeth bite into both the fastener and the mating surface, creating a mechanical lock that prevents loosening due to vibration, torque, or thermal cycling. They are commonly used in electronics, automotive assemblies, appliances, and industrial machinery where vibration resistance is essential. Internal tooth washers are preferred where a clean appearance matters, while external tooth washers provide stronger grip. Freeway Corporation manufactures tooth washers in multiple materials and configurations for OEM production runs.

What are chamfered washers and what applications require them?

Chamfered washers (also called double chamfer washers or beveled washers) feature a tapered or angled edge on one or both faces, designed to accommodate fasteners seated on sloped or irregular surfaces, or to allow for a flush, countersunk fit in precision assemblies. They are commonly specified in structural steel connections, heavy equipment, pipeline flanges, and precision mechanical assemblies where a flat washer would create uneven load distribution. Freeway Corporation’s double chamfer washers are manufactured to precise angular specifications, ensuring consistent seating and load transfer in demanding applications.

What are C-washers and what are they used for?

C-washers (also known as C-clips or slotted washers) are open-sided washers with a slot cut from the outer edge to the center hole, allowing them to be slid onto a shaft or bolt without fully removing the fastener. This design is particularly useful in maintenance, repair, and assembly operations where full disassembly is not practical or cost-effective. C-washers are commonly used in machinery, conveyors, agricultural equipment, and automotive applications where fast installation and removal are priorities. Freeway Corporation produces C-washers in multiple sizes and materials to meet OEM and MRO supply requirements.

Can Freeway Corporation produce high-volume precision turned parts?

Yes. Through its Triangle Machine Products division, Freeway Corporation specializes in high-volume CNC precision turning and secondary machining operations. The division produces complex turned components — including shafts, pins, bushings, fittings, and custom fasteners — to tight dimensional tolerances for industries such as automotive, fluid power, aerospace, and industrial equipment. Triangle Machine’s capabilities include CNC multi-spindle and single-spindle turning, as well as secondary operations such as threading, knurling, slotting, and cross-drilling. This makes Freeway a single-source supplier for both stamped and machined metal components.

What industries does Freeway Corporation serve with its stamping and machining capabilities?
