Anti-Loosening Double Nut Bolt

What is the PLB v2?
The PLB v2 has been designed to address the issues associated with the self-loosening of a bolted
joint. By design, the PLB v2 consists of a dual-thread screw shaft and two nuts of different thread
pitches. The first, or big lead nut on the shaft, is a multiplies-thread nut. The outer or secondary nut on
the shaft is a single-thread nut.
As for double nuts assembly, vibration initiates loosening with the inner nut. With PLB v2, the inner
nut’s advance is blocked by the slower-moving outer nut.
The mechanical lock is the secret to the PLB v2 Antiloosening design. No other fastener system in the world can make this offer. Most other anti-loosening kits use “friction” for their anti-loosening function
despite its uncertainty. However, PLB v2 has a reliable solution.

Environment-Friendly Zinc Aluminum Flake Coating for Corrosion Protection

Low-carbon steels corrode in most of the atmospheric environments when the relative humidity exceeds 60%. Corrosion is the destruction or deterioration of a material because of reaction with its environment. Most common corrosion control methods use coatings and conversion layers, which contain toxic and environmentally hazardous materials. There is a need to find nontoxic and environmental friendly alternatives compatible with current industrial techniques.

Spotlight on Thread Rolling Machinery & Tooling

If I were to rank fastener-making operations in order of importance, thread rolling would come in a close second to forming or heading. As the threads or roll forms produced by thread rolling machines and the corresponding tools like dies and attachments are the defining characteristics of many mechanical fasteners—rivets and pins being a few of the exceptions—the thread rolling process gets a lot of attention and space on the factory floor.

Fifty Years of Thread Rolling Excellence

This year, Tesker Manufacturing Corporation, Saukville, WI, USA, celebrates 50 years of thread rolling excellence. Redesign of All Rolling Machines – Tesker has now completed a redesign of all the company’s machines to feature servo-driven, electro-mechanical actuator on the press axis. This feature allows for high-speed actuation and complete push button control over size adjustments, force control and feed rates. Along with a new precision slide system, these features produce a highly rigid and simple to operate machine. Additionally, the elimination of the machine’s hydraulic system saves energy and maintenance as well as reduces noise.
