special bolt manufacturers

JM Hardware® carriage bolt has a square shoulder under a rounded head which resists turning when the nut is tightened or removed. They are good for wood-to-wood connections when the head may not be accessible for tightening. They may be used in the construction of docks, swing sets and decks as well as other surfaces where a smooth finish is needed.

As a custom fastener manufacturer, JM Hardware® can supply made to order custom engineered fasteners per your print. We handle a wide range of materials and custom made fasteners. We can make your fastener in carbon steel all the way to the exotic materials. We also have the capability to do large runs in the tens of thousands to short runs (washers, hex cap screws, and socket products). We can also handle many different plating specifications.  JM Hardware® can do simple zinc (including RoHS, black, yellow), black oxide, waxing, Teflon ™, Magni 565 and 560, Chrysler plating specifications, and much more. Our secondary operations include drilling holes, nylon patching, nylon pellets, and passivation to name a few. From small miniature machine screws to large diameter hex cap screws, we can supply your part per print.

JM Hardware® is a metal stamping manufacturer with equipment and expertise optimized for high-volume custom metal stamping production meeting ISO 9001 quality standards. Our custom metal stamping service uses a combination of high-speed presses and progressive dies to provide the most cost-effective solution for high volume manufacturing. When appropriate we design & build specialized manufacturing cells utilizing automation for high volume, low cost production.

Depending on the part’s shape and requirements custom machined parts might be made on a lathe, a milling machine, a stamping press, a press-brake, a precision shear, or machined on a myriad of other types of precision equipment. In many cases a custom machined part might pass through many of the operations listed before being finished. Although custom machined parts are typically more expensive than a mass-produced method, quite often the higher price is justified due to the fact that custom machined parts are generally more accurate, offer higher strength and/or integrity and can be made much faster than most other methods.

Acorn Nuts have a crown, or dome, covering. Since they have a closed top, acorn nuts are chosen for safety reasons. They prevent contact with external threads and protect the threads from rubbing against anything else. They can be reused, as their dome fastener head protects from stripping of screws and bolts. Additionally, the dome-like appearance gives a more finished look.Acorn nuts, also known as cap nuts or crown hex nuts, are used to protect or conceal threads on plumbing fixtures and industrial machinery. Fastener Solutions offers a variety of stainless steel, zinc, and nickel plated acorn nuts
