No Limit Manufacturing only sells products that meet our stringent performance requirements. We have been working with Optitorque for over 5 years. During that time, we worked together to develop top of the line fasteners to meet our demanding challenges that where required in our high hp diesel engine programs for truck and tractor pulling. From custom fasteners for our Cummins extreme rocker arm kits to head and main studs for 4200 hp single turbo Prostock engines. We needed repeated fitment, and reliability of performance. Optitorque stepped up to plate and met those challenges for us. That is why we can say with complete confidence they will give you the performance you need for your application. Here at No Limit Mfg., we have the knowledge and experience to get you the right fastener for application, and if we don’t have it today, we can work together to develop a great fastener for you. Here are some more great reasons to have confidence in these great fasteners.
100% manufactured with pride in the USA. Crafted from vacuum
melted micro alloyed American manufactured HSLA steel, each
fastener is heat treated and undergoes a proprietary tempering process to achieve a fine grain structure prior to thread rolling. The coarse threaded (block) end of the fastener features a bottoming boss eliminating the purchase of special tools to “hold” the fastener during installation.
These fasteners have 15% MORE clamp load than an ARP 2000.
These premium fasteners use ALL available factory block threads to distribute stress loads and are fully stress relieved prior to centerless grounding for maximum straightness.
The Torque Master Series fasteners feature the greatest stretch area in their price class optimizing cycle fatigue properties.
Each fastener is hot temperature oiled and brilliant black oxide coated for protection.
The kit contains:
Forged high strength heat treated 12-point nuts and precision ground load distributing washers, ensuring a uniform clamp load, TrueTorq+ ® fastener assembly lubricant and installation procedures.
**Fastener lengths are engineered from O.E.M. production parts
and machine tolerances. Aftermarket or custom manufactured
parts may require fitment modifications or length alterations**
