Leading Custom Fastener Manufacturer and Supplier

Filters Materials Available Hastelloy Corrosion-resistant Hastelloy alloys are suited for a variety of corrosive acid environments. Hastelloy is one of the most versatile corrosion-resistant alloys with strengths including excellent stress cracking and localized corrosion resistance.

Inconel alloys are oxidation and corrosion-resistant materials that excel in high pressure and temperature environments. Their strength is at elevated temperatures while still maintaining good corrosion resistance.

Monel fasteners exhibit good corrosion resistance over a wide range of temperatures. Monel fasteners are often used in applications involving hydrofluoric acid due to their exceptional resistance. They are often utilized in marine and oil extraction and refinery processes.

Titanium fasteners offer benefits in strength, weight, and corrosion resistance. They are necessary a high strength to weight ratio and resistance to corrosion and stress cracking is needed.

Alloy 20 fasteners are often used in mid-level corrosive environments due to their corrosive resistance above steel, but not at the performance level of nickel-based alloys such as Hastelloy. Its benefit is that it can still provide moderate corrosion resistance for a cost less than that of its higher-performance competitors.

Kenneth G. Lilly fasteners offer ASTM certified material with corresponding certified material test reports at request.

We frequently cut studs of a predetermined length from threaded or non-threaded rods. We can also cut preexisting bolts/cap screws down to a specified size for a customer.

Head markings can be applied to products including, but not limited to, Grade, MFG, Lot Trace Code, Lot Number, etc.

A chamfered edge not only provides a finished edge, but increases practicality and protect from damage.

Standard or custom threading can be applied to a variety of fasteners including round bar, threaded rod, studs, headed bolts, etc.

Polytetrafluoroethylene is a synthetic fluoropolymer of tetrafluoroethylene. PTFE has a wide variety of applications. Widely known for its non-stick properties, its also hydrophobic, resistant to higher temperatures, non-wetting, and high density.

Coating a substrate metal (steel, iron, etc.) with a layer of zinc to protect the underlying material from corrosion.

A metallurgical process that typically involves the application of heat, to extreme temperatures to achieve the hardening or softening of a material. We use a variety of techniques depending on the customers’ requirements including annealing, case hardening, quenching, carburizing, etc.
