Domestic Manufactured and Direct Import Bolts
Custom-machined bolts are precision-engineered fasteners that match exact specifications for high-performance applications. Whether you’re designing for strength, corrosion resistance, or unique dimensions, these bolts deliver what off-the-shelf options simply can’t. Abbott Interfast proudly manufactures a wide range of custom hex bolts, flange bolts, and other fasteners to meet your requirements with speed and accuracy.
The Functionality Behind Custom-Machined Bolts
A bolt is a threaded fastener that typically pairs with a nut to join two or more components. Custom-machined bolts offer greater precision, tighter tolerances, and material flexibility compared to standard, off-the-shelf options.
Abbott Interfast manufactures custom bolts for OEMs and businesses nationwide. Our capabilities allow for made-to-order bolts in both inch and metric sizing, with production options for small or high-volume orders.
Because you can remove and replace these bolts easily, they’re ideal for assemblies that require ongoing maintenance or repairs.
Our Selection of Custom Bolts
We produce made-to-order bolts in both inch and metric sizes using high-quality materials, including carbon steel, alloy steel, stainless steel, aluminum, A286, and brass.
Our team also provides secondary operations such as nylon patching, heat treating, drilling, packing, and bagging or kitting, ensuring each order is ready for assembly and delivery.
