Aerospace Fasteners

 The special characteristic of Aerospace products include lightweight and durability. These help to withstand high pressure (for eg while exiting earth’s atmosphere) and higher temperature (for eg exposure to burning rocket fuel).

Over the years, various equipment and metal treatment methods have been developed to get high quality aerospace fasteners to assist planes and space vehicles to be airborne with minimal stress.

We are stocking the following aerospace products. The high quality of these is synonymous with our Company name.

Aerospace Screws in SS304: The head is at a special 100 degree angle which reduces the height and allows the screw to be used in narrow spaces.

Countersunk Screws (Also know as a flat head screw) are used where the finished surfaces require a neat and flush fastening unit. The countersunk portion offers good centering possibilities.

100° special flat head screws have been developed for use In soft materials to distribute pressure over a larger and less angular surface. Very well adapted for use with thin aluminium, soft plastics, etc. MIL-STD-1515 “Fastener Systems for Aerospace” requires 100 degree countersunk screws. Manufactured as per ISO-5856 and IS:15437 and  available in AISI-304 grade.

Titanium Alloys Fasteners available in ready stock:

Wire Thread Inserts in Phospor Bronze

Specialised Phospor bronze inserts

Phosphor bronze is an alloy of copper, tin and phosphorus – 0.5–11% tin and 0.01–0.35% phosphorus.

The tin strengthens the alloy by increasing its corrosion resistance. The phosphorus contributes by increasing the wear resistance and stiffness of the alloy.

These alloys become special in their utility. It is unmatched it its toughness, strength, low coefficient of friction, and fine grain. The phosphorus reduces the viscosity of the molten alloy, which makes it easier and cleaner to cast and reduces grain boundaries between crystallites.


Wire Thread Inserts in SS 316

Wire thread inserts for precision industry are manufactured to high standards.
Thread inserts in SS 316 are:
Highly corrosion resistant;
Have low thread friction;
Useful where high alloyed CrNi steel screws are needed.Suitability
– Aerospace Industry
– Marine Industry
– in lightweight construction
– for corrosion resistance due to sea water
– corrosion resistance due to high chlorine containing water
