Heavy duty and engineering fasteners built to your drawing. As a specialist Special Fasteners Manufacturer Chennai, we produce eye bolts, U-bolts, hook bolts, T-bolts, clevis pins and fully custom-engineered components in any grade and any finish.
Standard catalogue bolts do not always fit specialised machinery or structural assemblies. As an established Special Fasteners Manufacturer Chennai, Mishkat Pipe Fittings Co. produces eye bolts, U-bolts, hook bolts, T-bolts, clevis pins and fully custom components manufactured to customer drawings or samples.
Choosing an experienced Special Fasteners Manufacturer Chennai means your non-standard components arrive dimensionally correct the first time. We manufacture virtually any fastener profile in carbon steel, stainless steel, alloy steel and brass. If you have a drawing, a sample, or even a rough sketch, our team will review and quote — reverse engineering from physical samples is also accepted.
What We Manufacture
Lifting and Rigging: Eye bolts and hook bolts to DIN 580 and BS 4278 for crane, hoist and lifting-point duty.
Pipe and Equipment Clamping: U-bolts and T-bolts sized to pipe OD for supports, saddles and structural clamping.
Pinned Connections: Clevis pins and split-pin assemblies to ISO 2341 for linkage and hinge applications.
Fully Custom Profiles: Any head form, thread pitch, bend geometry or length made to your engineering drawing.

Heavy Duty
Heavy Duty Fasteners Chennai
Lifting points, structural clamps and machinery mounts carry loads that ordinary bolts cannot safely hold. Our Heavy Duty Fasteners Chennai range is manufactured from high tensile and alloy steel bar stock, then heat treated to hold its strength under shock loading, sustained tension and heavy vibration.
Every batch of Heavy Duty Fasteners Chennai is checked for thread accuracy, hardness and dimensional tolerance before dispatch. Protective finishes — hot-dip galvanizing, zinc plating and black oxide — keep components serviceable through years of outdoor and marine exposure.
Proof Load Tested: Lifting-duty eye bolts and hook bolts are proof tested and certified on request.
Large Diameter Capability: Heavy sections produced well beyond common catalogue sizes.
Corrosion Protection: HDG and zinc finishes specified to suit the service environment.
Full Documentation: Mill Test Certificates and dimensional inspection reports with every order.
Engineering
Engineering Fasteners Chennai
OEM equipment builders and plant engineers frequently need components that no catalogue lists. Our Engineering Fasteners Chennai service covers design-to-drawing manufacturing — uncommon thread pitches, unusual head geometry, bent and formed profiles, and close-tolerance machined parts.
Working with a dedicated Engineering Fasteners Chennai supplier removes long import lead times and keeps your maintenance schedule on track. We handle both single replacement pieces for urgent breakdowns and repeat production batches for series equipment builds.
Reverse Engineering: Send a worn sample and we reproduce it dimensionally.
Material Flexibility: Carbon steel, SS 304/316, alloy steel, duplex and brass.
Prototype to Production: One-off trial pieces through to scheduled bulk releases.
Local Chennai Manufacturing: Short lead times and direct technical discussion with our works team.

What does a Special Fasteners Manufacturer Chennai produce?
A Special Fasteners Manufacturer Chennai makes non-catalogue components — eye bolts, U-bolts, hook bolts, T-bolts, clevis pins and fully custom profiles built to drawing. We manufacture in carbon steel, stainless steel, alloy steel and brass, in any head form, thread pitch or bend geometry you specify.
What makes a fastener heavy duty?
Heavy duty fasteners are made from high tensile or alloy steel bar and heat treated to hold strength under shock loading, sustained tension and heavy vibration. Our Heavy Duty Fasteners Chennai range is checked for thread accuracy, hardness and dimensional tolerance, with lifting-duty items proof tested and certified on request.
Do you make engineering fasteners for OEM equipment?
Yes. Our Engineering Fasteners Chennai service covers design-to-drawing manufacturing for OEM builders and plant engineers — uncommon thread pitches, unusual head geometry, formed profiles and close-tolerance machined parts. We handle single urgent replacements as well as repeat production batches.
Can you manufacture custom fasteners to my drawing?
Yes — this is our core strength. Send your engineering drawing (PDF, DWG or DXF), a sample component, or a detailed specification to sales@mishkatfittings.com and we'll provide a quotation. We can also reverse-engineer from a physical sample.
What is the minimum order quantity for custom fasteners?
MOQ for custom fasteners is 150 pieces.
Do you supply WLL-rated and certified eye bolts?
Yes — eye bolts and lifting hardware undergo hardness, tensile and proof-load testing, with WLL certification available on request. LOLER compliance for UK/EU export is not currently offered.
What is the lead time for custom special fasteners?
Lead time for custom items is 10–12 days.
Can you supply U-bolts for pipe clamp assemblies?
Yes — round, square and J-bend U-bolts in standard pipe ODs are available. Custom pipe ODs and non-standard bend radii can be manufactured. Supplied with nuts and washers on request.
Do you supply stainless steel special fasteners?
SS 304, SS 316, Duplex SS 2205 and Super Duplex 2507 are all available for eye bolts, U-bolts, hook bolts and clevis pins, manufactured to order — none are held as stock items.
Can you supply CE-marked lifting equipment?
Yes — CE marking is available for eye bolts and lifting hardware exported to the UK/EU. LOLER certification is not currently offered.
Do you accept sample-based orders (reverse engineering)?
Yes — send us a sample part or a sketch with key dimensions and we will manufacture to match. This is commonly used for obsolete or non-standard fasteners where drawings are unavailable.
Need a Custom Fastener?
Send us your drawing or sample — we can manufacture to your exact specification in any grade, any finish.
