Xylan® Coatings are a family of fluoropolymer coatings designed for use on various types of nuts bolts studs and all other types of threaded fasteners, including xylan coated bolts to prevent corrosion.
Most Xylan® coatings contain PTFE or other types of lubricants and are applied in thin films. Xylan coating is a dry film lubricant.
We provide coated Astm grade fasteners coated with Xylan for Offshore oil production companies under third party inspection.

We provide Galvanized Stud as per customer's requirement. Most ferrous materials are suitable for hot dip galvanizing. Full thread studs can be protected by hot dip galvanizing. Structural steel shapes, including those of high strength low alloy materials, are hot dip galvanized after fabrication to obtain the long lasting protection afforded by the zinc coating.
Though most ferrous materials can be hot dip galvanized, the characteristics of the galvanized coating will be primarily a function of the chemical composition of the material.
The galvanized coating has as its basis a reaction between steel and molten zinc resulting in the formation of a series of zinc-iron alloy layers, which are normally covered by a layer of solidified zinc. For most hot rolled steels the zinc-iron alloy portion of the coating will represent 50 to 70 percent of the total coating thickness.

The Chemical Anchor Stud is a chisel ended anchor for use with any of our injection systems and glass capsules in masonry and concrete. On installation, the stud becomes chemically bonded to the base material. Notably, the xing method imposes no expansion stress on the base material and is ideal for shock or vibratory loading and for softer or low-density building materials where expansion stresses would normally result in failure. The method also gives an exceptional performance for the close center and close to edge xing. The nut may be removed and replaced without aecting the anchorage. The chemical anchor CAS is supplied complete with high tensile hex nut and plain washer in addition to one external hex drive adapter in each box.

Hydrogen Embrittlement:
Hydrogen embrittlement is a ductile-to-brittle change which occurs in certain high strength steels. Hydrogen released during the pickling operation can cause this embrittlement. This hydrogen can be absorbed into a steel during the acid pickling but at galvanizing temperatures, it is generally expelled from the steel.
Hydrogen embrittlement is not common, but precautions should be taken, particularly if the steel involved has an ultimate tensile strength exceeding approximately 150,000 psi. If high strength steels are to be processed, grit blasting instead of acid pickling is recommended to minimize the likelihood of hydrogen embrittlement.
We provide HDG UPTO 100 microns as per customer''s requirement. We also have in-house coating thickness checking instrument.

Stainless steel is one of the most common materials used for fasteners due to its stability, strength and anti-corrosive and high heat properties. Its combination of the strength of steel with its superior anti-corrosion and heat-resistance properties result in a versatile, economic alloy.
Alloy Steel Nuts is available in three main grades - austenitic (300 series), martensitic and duplex. The 300 series of stainless steel is the most common and is used for sanitary applications due to its ease of cleaning and corrosion resistance. Martensitic stainless steel screws, bolts, nuts, and studs are extremely strong and easily machined.
