The phrase “the nuts and bolts” refers to the basics of something. Nuts and bolts may be basic, but their importance is critical. As we frequently say, small things keep big things from failing. Dunham Products manufactures a wide range of nuts and bolts and can produce any specifications that you require for your application or project. In addition, we can handle any type of modification of standard fasteners because we make your connections stronger. We can do complete manufacturing or any type of modification, including: Drilling and tapping Thread re-rolling Milling Slotting Dunham Products manufactures nuts and bolts in the following materials, including DFARS (Defense Federal Acquisition Regulation Supplement) and RoHS (Restriction of Hazardous Substances Directive) compliant: Ferrous: Alloy Steels Carbon Steels Monel® Super Alloys Stainless Steel Non-Ferrous: Aluminum Brass Bronze Copper Titanium Specialty: Nylon Fiberglass Ceramic

Just about every mechanical assembly makes use of fasteners to attach components together in some way, shape or form. Small fasteners keep big things from failing. In fact, fastener failures are the leading cause of mechanical malfunctions. Fasteners may be small in size, but they are large in importance. Dunham Products manufactures a wide range of high strength fasteners, from standard products to specialty fasteners. In addition, we can handle any type of modification of standard fasteners because we make your connections stronger. Dunham Products manufactures high strength fasteners in the following materials, including DFARS (Defense Federal Acquisition Regulation Supplement) and RoHS (Restriction of Hazardous Substances Directive) compliant: Ferrous: Alloy Steels Carbon Steels Monel® Super Alloys Stainless Steel Non-Ferrous: Aluminum Brass Bronze Copper Titanium

Dunham Products manufactures washers, spacers and bushings to use with our threaded fasteners. Washers help to distribute load, reduce vibration, and wear. Spacers are used when additional space between objects is required. Bushings are sleeves which reduce friction and limit movement on one or more axis, while allowing free directional movement. Dunham Products manufactures spacers and bushings in the following materials, including DFARS (Defense Federal Acquisition Regulation Supplement) and RoHS (Restriction of Hazardous Substances Directive) compliant: Ferrous: Alloy Steels Carbon Steels Monel® Super Alloys Stainless Steel Non-Ferrous: Aluminum Brass Bronze Copper Titanium Specialty: Nylon Fiberglass Ceramic We can also produce many types of internal geometry, and can offer these modifications: Shorten length Open hole diameter (ID) Reduce body diameter (OD) Cross-drilling

Dunham Products began its life producing studs used in the manufacture of aircraft fuel pumps. Today, we continue our tradition of strength producing studs for the aerospace industry. Studs are externally threaded fasteners, usually threaded at both ends, and do not have a head. Studs are frequently preferred for aerospace fastener applications because the stud and nut configuration is stronger than using a bolt. When using a bolt, you are wearing out the threads in the tapped hole; when using a stud, you are only wearing out the threads on the stud nut end. Dunham Products manufactures studs in the following materials, including DFARS (Defense Federal Acquisition Regulation Supplement) and RoHS (Restriction of Hazardous Substances Directive) compliant: Ferrous: Alloy Steels Carbon Steels Monel® Super Alloys Stainless Steel Non-Ferrous: Aluminum Brass Bronze Copper Titanium In addition, Dunham produces studs in the following configurations: Fully-threaded Single- and double-ended Tap end studs Standard or special pitch diameters available Standard and metric sizes Dunham can thread roll after heat-treating, which increases their strength, and are QSLM (Qualified Suppliers List for Manufacturers) certified for Class 2 and 3 Threaded Fasteners.
