It is understandable to prefer that a single torque tension modifier could be utilized for various applications by diluting the solution to adjust the coefficient of friction (CoF). However, this would not work to achieve desired goals because the final CoF depends on multiple factors beyond just the concentration. In order to understand these factors, we should first consider the functional application of the coating and its role in the plating process.

As Tier One suppliers to OEMs, fastener manufacturers are tasked with controlling aspects beyond pitch diameter, head dimensions and other characteristics. Most fasteners use finishes ranging from basic phosphate and oil to high-performance zinc flake coatings and zinc-nickel. In addition, downstream operations such as sorting and patching are required to meet OEM requirements, adding complexity to the supply chain.

Since Fastener Technology International (FTI) published its International Fastener Expo 2026 Preview in the August/September 2026 issue, additional details have been announced for the event, including the complete educational program and the recipients of the 2026 IFE industry awards. The show is packed with activities and exhibitors. The latest details can be found at www.fastenershows.com.

In steel processing, annealing is one of the most critical heat-treatment processes used to increase the ductility, softness and mechanical properties of steel wires. Efficient loading plays a pivotal role in achieving uniform heat distribution, reducing operational costs and increasing overall plant throughput. Charge carriers are heavy-duty structural fixtures designed for stacking wire coils and bundles inside bell furnace units during high-temperature annealing operations.

Precision fasteners often require secondary CNC turning after cold heading, forging or forming. Shoulders, bearing faces, grooves, bores, reliefs and thread-preparation diameters may need machining before threading, coating or final inspection. Repeatability depends on more than CNC positioning accuracy. Blank variation, datum selection, workholding, machining sequence, tool condition and machine temperature can all influence the finished geometry.

The companies best prepared for artifi cial intelligence will not necessarily have the newest models. They will have the clearest descriptions, the smartest tags and the cleanest route from information to action. Anders Green has been speaking at fastener expos for three years now on the topics of technology and AI.

The world is constantly changing. Every day we face new challenges that require new solutions. What applies to our everyday lives also applies to the world of fasteners. The requirements OEMs place on fastening properties are constantly increasing, with particular focus on process reliability. A reliable screw connection helps ensure that faults occur less frequently and can be rectified more quickly. This helps processes run smoothly, resulting in less time-consuming and costly downtime.

In high-strength construction, energy, and manufacturing projects, these sudden failures happen far more often than they should. The hidden culprit isn’t bad installation or poor design; it’s a stealthy condition called hydrogen embrittlement (HE). When high-strength steel fasteners—such as Grade 8 bolts, structural nuts, hardened washers and socket screws—are plated with zinc for rust protection, microscopic hydrogen atoms can sneak inside the steel.

In today’s fastener industry, production lot sizes for individual part numbers are becoming smaller and more fragmented. This makes it increasingly difficult for manufacturers to justify an investment in a high-performance 100% automatic sorting machine because return on investment becomes harder to achieve as volumes shrink. As highlighted in this case study, sorting machines are also used by distributors and third-party sorting services.

Asahi Sunac Corporation in Japan has continued to supply 2-die, 2-blow headers to the U.S. market, beginning with the AOT/AT series under its former name, Asahi Okuma. These machines were in high demand among U.S. customers, and the lineup continued with their successor, the ST series, which remains available today. Asahi Sunac has responded to changing market needs by expanding its product lineup.
