Fasteners: Metal related categories
 | Thread Rolled Bar & Rod
Precision thread rolling techniques employed at Rolled Threads Unlimited produces bar and rod with superior strength, finish and dimensional integrity with accurate lead tolerances. We offer the broadest size range in the industry: .0312” thru 7” diameter. All the major thread forms are rolled: Unified, UNJ, Metric, Acme, Trapezoidal, Worms, Knurls and special configurations. Carbon and alloy steel, stainless steel, nickel alloys, brass and aluminum are available in all the thread forms. |
| Unified Threaded Rod
Unified threaded bar & rod is available as coarse thread ( UNC) and fine thread (UNF) series. Thread pitches from 4 TPI to 100 TPI and finer. Special lengths up to 40 Ft. |
 | Unified UNJ Threads
Fasteners for demanding applications are often specified with the UNJ thread form. The controlled and more generously radius root enhances the fatigue resistance of fasteners. Applications include aerospace and engine hardware.
Unified UNJ threads are offered in four different types of pitches including
Coarse pitches
Fine pitches
Extra fine pitches
Constant pitches |
| Acme Threaded Bar and Rod
The acme product is rolled in diameters from 1/8” to 7 1/2” and lengths to 40 Ft. Right and left hand acme bar is available as well as multiple leads, stub acme forms and classes 2C, 2G, 3C & 3G. Precision lead screw applications are accommodated by lead accuracy capability as close as .003/ft and straightness to .001/inch. Carbon steel, heat treated alloys, stainless steel, aluminum and nickel alloys are rolled in the acme forms. |
| Trapezoidal Threaded Bar and Rod
Trapezoidal threads have a 30 degree included angle versus 29 degrees for the acme form. Rolled Threads produces trapezoidal bar in the same size ranges and material varieties as acme bar.
The thread pitch ranges from 1mm through 10mm for all RH and LH operations. The diameter ranges from 4mm through 170mm and the available classes of fit are 6e, 7e, and 8c. We follow an ISO metric profile for our trapezoidal threaded rods. |
| Metric Threaded Bar and Rod
Our metric threaded fasteners are used in a wide variety of applications. Rolled Threads has tooling available to make metric sizes in all the coarse and fine thread pitches. Size capabilities range from 2mm thru 160mm diameter and 8mm to .4mm pitch. Right hand and left hand. |
 | Specialty Fasteners
Rolled Threads Unlimited machines and thread rolls specialty fasteners including hex head bolts, cap screws, fully threaded studs, double end studs and nuts. With our extensive machining capabilities we can make custom fasteners to your prints.
Fasteners can be made to your own specification or industry standards including:
ASTM A-193
ASTM A354
SAE J-429
ASME 818.2.1-1996
ASTMA320/320M
Fasteners provide a connective mechanism to securely hold two different materials together. The overall efficiency of a typical fastener depends on the strength and resistance provided by the threads in it. We offer fasteners of part sizes up to 7 ½” diameter. There are different forms of industrial fasteners available today like aerospace fasteners, metal fasteners, plastic fasteners, stainless steel fasteners, metric fasteners and composite industrial fasteners.
Machined fasteners that we provide find their usage in a wide variety of applications like
Pool cues
Gas and oil equipments
Wind turbines
Outboard motors
Generators
Railroad equipment
At Rolled Threads Unlimited, we have a specialized quality management system that meets all ISO 9001: 2001 certified standards, and controls any outsourced processes that affect product conformity requirements. We follow a stringent quality management system that helps to continuously improve performance standards. The different methods and processes that we handle are all quality assured through continuous monitoring, measurement and analysis. We are committed to quality policies and objectives to meet all customer demands and requirements. |
 | Double Ended Studs
Rolled Threads Unlimited offers custom made double ended studs in Unified, UNJ , Metric and MJ forms from 1/8” thru 7 ½” diameters . Classes of fit include 1A,2A 3A and interference. We capable of rolling studs with hardness of RC 40 and higher.
Double ends can be produced to these and many other specifications:
ASTM A-193
ASTM A354
