Manufacturing Capabilities

Below are some of the manufacturing capabilities DAN-LOC can offer.

• Cutting - High-speed band saws cut threaded bar to discrete bolt lengths.
• Threading - roll form threading, cut threading, and oversize tapping of nuts for coatings.
• Blast Cleaning - coiled steel bar is blast cleaned before drawing.
• Wire Drawing - draws and shears to length discrete bolt lengths.
• CNC machining - lathes, mills.
• Materials Analysis - all incoming raw material is positively identified using X-ray fluorescence technology.
• Metals Physical Properties Analysis - DAN-LOC's onsite laboratory performs tensile, Charpy, and proof load testing of products.
• Hardness Testing - Rockwell, Brinell, and Eddy Current hardness evaluations.
• Heat Treating/Modifying - Dan-Loc operates three furnaces: capacity: 3,000 lbs./hr.
• Coating/Plating - zinc, cadmium, moly disufide, chrome, silver, gold, Xylan®, Xylar®, Teflon®, and other specialty plating/coating.

DAN-LOC SPECIAL PRODUCTS

"Specials" are defined as manufactured bolts or other products whose final configurations are non-traditional with respect to industry association standards featured by ASTM, SAE, or ASME. They may consist of atypical diameters, lengths, or other attributes such as hex flats, milled surfaces, grooves, contours, special threads, or any number of geometric variations from traditional products that involve custom engineering. They also may require fabrication from exotic materials, include unique coatings, are subjected to specialized treatments such as shot peening, require rigorous engineering focus, or exhibit a variety of characteristics that do not fall neatly within the definition of standard products. Dan-Loc is capable of manufacturing these special products in addition to its standard product offerings.

Dan-Loc predominantly uses high-quality U.S. produced raw materials, and a very limited amount of imported materials from trusted suppliers with a track record for providing exceptional quality products. (An example is the sourcing of nuts from Hamanaka, a premier Japanese manufacturer.) Even then, DAN-LOC's rigorous quality program subjects these products to random proof-load testing to ensure product integrity. Dan-Loc operates under a DNV certified ISO 9001:2008 quality program, and also manufactures under American Petroleum Institute license (API-6A) for pressure-containing wellhead components (ring type joint gaskets).
