Many imperial threads sizes that are now antiquated caused by changes in demand patterns from countries such as the USA who now drifting towards metric products. This increasing globalization of metric threaded fasteners does not necessarily mean that all variations are commonly available. The team at Challenge (Europe) Ltd are well use to this situation and carry extensive stocks of standard sizes of industrial screws plus a wide experience in supply of non-standard sizes, threads, lengths and materials. Kevin Moorcroft explained,

“We find that standard sizes of metric products have grown extensively. ISO standards now cover a whole range of products complimentary to old imperial sizes, as well as expanding on the original ranges of metric fasteners, e.g. metric socket head cap screws once only available in 12.9 grade are now offered under the ISO standard in 8.8, 10.9 and 12.9 grades to suit a wider range of applications with varying requirements of tensile strength.”

However, head configuration can have an effect on the size of metric fastener that can be used. For example, if you use a M6 bolt with a hex head but find conventional spanner access limited, you could then use the recessed drives such as a hexagon (socket) or multiple splined variants. Another substitute is to go to a smaller diameter with an upgrade in material specification, although this may lack a greater deal of examination in order to avoid non-preferred diameters such as M7, M9, etc.

On March 6th 2017 there was an article on Fastener World Inc that talks about how Yudensha, Co., Ltd and Kishiwada Steel Co., Ltd worked together in order to make a ground breaking surface treatment technology that prevents stainless steel bolt and nut seizures. This new technology will be available through the distribution network and Yura Sansho Co., Ltd. The article listed nine items about the new nuts. Here is what the article said.

  1. No sign of seizure after 8 times of seizure tests, or when fastening the M8 anti seizure nut with 110N m torque
  2. Heat resistance range of -50 degrees to 400 degrees Celsius
  3. Passed the JIS Z 2371 salt spray test.
  4. Galvanic corrosion might occur but doesn’t affect the ability to prevent seizure at all
  5. Coefficient of friction 0.38 under fixed axial force; 0.32 under fixed torque
  6. Axial force 5.0kN under fixed torque. Increasing axial force due to reduced coefficient of friction
  7. Substantial reduce bolt replacement
  8. Dry heat treatment meaning the anti seizure nut can be used immediately after treatment
  9. High coating adhesion meaning anti seizure nut can be used repeatedly.

pros and cons of anchor fasteners
Fixings for any application is very important when it comes to safety, and there is a whole array of fixing systems to choose from. However, those with experience can choose quickly between chemical and mechanical anchors. Mechanical anchors can be split into two categories,expansion anchors and non-expansion anchors. Expansion anchors can be any of different types of anchors such as stud anchors, shield anchors, sleeve anchors and a bunch more.These anchors use the expansion method to hold any two pieces together. Unfortunately, expansion anchors have their cons because they can be limited to what type of material they are used in.

For example,if you use an expansion anchor in a brickwork or stonework then it might cause that material to crack or simply crush. In that case, non-expansion anchors can be a better alternative. Chemical anchors don’t have the complications a mechanical anchor has and can be very useful at closer edge and distances in material such as concrete, so for example you can create a small space between two materials and still create a very strong connection between the two. For example in concrete. Anchor Fasteners is a big industry and the demand for them is becoming much higher in all manufacturing industries.

japanese tennis wheelchairs

President and CEO of NSK Ltd. Toshihiro Uchiyama had the great pleasure of presenting one of the company’s latest innovative bearing. This specific bearing has been customized and designed for greater performance for competitive Tennis Wheelchairs. Recently the Tokyo Institute of technology embraced the new innovative bearing that will used for an enhanced range of motion for the auxiliary caster component. An additional alteration was put into play when the tennis players of the institution requested for the bearings to be of a lightweight design and minimize friction to its lowest possibility.NSK has completed much research in many aspects and areas of bearings on a wheelchair and has discovered that many of the issues they are faced with are quick changeable properties. Gathering information such as

“speed, load, impact, and acceleration/deceleration at actual competitions and practice sessions, used this to determine optimal bearing specifications, and then developed a prototype.”

All the research quickly influenced the design of the latest bearing to be able enhance not only competitive wheelchairs but everyday wheelchairs as well.Prior to the innovative bearing NSK was not known in the market for their agile parts but has sent a message with their latest piece.NSK is known for being Japans first bearing manufacturer in the country and countries industry. They have been in business and reduced the amount of friction loss since Nov 08, 1916. They are a company that is headquartered in Shinagawa, Japan and currently are involved with business worldwide. NSK initial goal is to be able to provide the best possible competitive equipment that is to be reliable, agile and will perform in the best possible at any given time. NSK is well prepared to continue to provide the globe with high technology around the globe.

Airbus drilling technology for rivet hole

Airbus Group has just announced that they are putting the finishing touches on a brand new ground-breaking fully-automated technology for drilling rivet holes. This new technology accomplishes this by combining a magnetically-levitated drill spindle with a state of the art articulated robot system. This is especially important because during the drilling of rivet holes shards can become lodged in the drill bit flutes damaging it in the process.

This vital component of airplane manufacturing often requires frequent tool changes which cost time as well as costly delays in the manufacturing process. On top of that imperfect precision of semi-automated and manual processes will cause inconsistencies in the hole diameter and further damage the material.

The new Airbus fully-automated electrical vibration driller takes a superimposed oscillation pattern in order to move the drill bit in and out of the material and creates significantly lower temperatures and leads to less reduction in burr formations around the holes with the newly developed spindle fractures being extracted without residue.

All of this produces a processing time of fifty percent shorter for thick titanium packages and less wear and tear on the tool. Airbus is expected to debut the vibrating spindle set at the company’s Bremen facilities in Germany and is hot on the heels of the unveiling of Airbus’ enhanced center wing box design earlier in the month which continues the trend of exciting developments and debuts by Airbus this past year.
