Higher value for your money

Equipped with dimensional accuracy & higher strength levels, AL RASHED FASTENERS offer you substantial cost saving in the joint preparation & assembly stages there by raising the value of your money. The following rules establish this value appreciation.

• Cost of fasteners is disproportionate with their utility. Consequently, the reliability of 95% cost, of the project rests on 5% cost of the fasteners giving them high value responsibility in industry.
• Fasteners cost is a minor percentage (5%) of that of the whole fastening system i.e. In place cost of the system (IPC), itself.
• The IPC cost, for a given joint, can be reduced by using lesser bolts or smaller diameter bolts. This can only be done through smaller fasteners with highest tensile strength. Obvious advantage would be a lighter and smaller assembly.
• In which event costs would be cut under all the heads of IPC making the assembly economical.

In Place Cost

• Purchase
• Storage
• Preparation (drilling, tapping etc.)
• Cleaning
• Picking
• Assembly
• Inspection
• Maintenance

To reduce the in-place cost, it is, therefore, obvious that in a given joint, either the number of bolts used should be reduced, or diameters of the bolts used should be reduced. This is possible by selecting smaller size fasteners with higher tensile strengths. The added advantage will be a lighter and smaller assembly.

Equipped with dimensional accuracy and higher strength levels, AL RASHED FASTENERS offer you substantial cost saving in the fastening assembly. Value of your money is raised after heeding to the following rules.

Advantage of High Tensile Fasteners

Maximum of strength with minimum of fasteners

High tensile Hex Nuts are forged to precision grade dimensions to ensure smooth assembly. In addition, heat treatment is done to suit the chemistry of every part of steel. This imparts optimum mechanical properties to ensure that correct tightening torque can be applied to fulfill design requirements.

Advantages

• Reduced number of bolts
• Reduced bolt size
• Less numbers of holes
• Reduced size of holes
• Reduced assembly cost
• Reduced maintenance cost

Comparing strength of high tensile and ordinary mild steel bolts

It is obvious from this above chart that high tensile bolt of property class 10.9 is approximately four times stronger that an ordinary mild steel bolt of property class 4.6. This extra strength of high tensile bolt can be used to upgrade an assembled joint from a low tensile one to a high tensile one to gain all the advantages described.

High tensile Hex bolts and nuts by AL RASHED are used in a wide range of applications including automotive, structures, machine building and electrical industries. Their special design and properties offer several benefits.

Rolled Threads

Threads are rolled, not cut or ground. Rolled threads are more uniform and have closer tolerances. Contour following flow eliminate planes of weakness and improve fatigue strength.

Dimension Tolerance

They are held to precision grade to give maximum cross-section area to ensure smooth assembly.

Heat Treatment

Heat treated in a controlled atmosphere to achieve maximum strength and toughness.

Forged Heads

In contrast to conventional mechanical bolts, which cut metal fibers, break fiber flow lines and create planes of weakness at stress points, controlled forging give uniform grain flow with unbroken fiber lines, make heads stronger; besides preventing fatigue failure in the vital area.

Special Under-Head Fillet Design

Provides smooth transition in the area from head to shank, reduces stress concentrations; improves fatigue life.
