Export-Grade Fastener Solutions
Precision Industrial Screws Manufacturer in India
Stud Bolt India is an ISO 9001:2015 certified manufacturer and exporter of high-precision industrial screws designed for critical engineering, oil & gas, petrochemical, aerospace, marine, and power generation projects. Operating from our advanced manufacturing facilities in Mumbai, we produce an extensive line of metric and imperial screws strictly conforming to ASME, DIN, ISO, and BS specifications.
Our comprehensive production capabilities cover stainless steel screws (304, 316, 317L, 904L), high-tensile alloy steel screws (Grade 8.8, 10.9, 12.9), duplex & super duplex steel screws (UNS S31803 / S32750), and nickel alloy screws (Inconel, Monel, Hastelloy, Titanium). Engineered to withstand high operational stress, corrosive process environments, and extreme temperatures, every batch undergoes 100% thread gauging and material verification before international dispatch.
Comprehensive Types of Industrial Screws
We manufacture a wide spectrum of screw configurations engineered for superior clamping force, corrosion resistance, and operational longevity:
Wood Screws
Coarse thread pitch with sharp point for timber & heavy composite structural jointing.
Thread Cutting Screws
Hardened cutting edges that generate mating threads in heavy sheet metals & castings.
Mushroom Head Screws
Low-profile rounded head designed for smooth aesthetic surface finish & snag-free assembly.
Hex Socket Cap Screws
High-tensile internal hex drive screws ideal for compact machinery & high-stress joints.
Square Head Screws
Heavy-duty square drive offering high tightening torque for industrial machinery.
Set Screws (Grub Screws)
Headless design with cup, flat, or cone points for securing pulleys, gears & shafts.
Butterfly (Thumb) Screws
Winged head design allowing easy tool-free hand adjustment in field applications.
Hammer Head Screws
T-slot drop-in locking screws engineered for modular aluminum framing & structural channels.
Dome Head Screws
Smooth raised head profile providing even load distribution and enhanced safety.
Oval Head Screws
Countersunk design with rounded top, combining flush seating with decorative appearance.
Flange Head Screws
Integrated washer face spreading clamping loads over a wider surface area.

E-E-A-T Quality Commitment
Stringent Quality Inspection & Material Traceability
At Stud Bolt India, quality is integral to our manufacturing process. International buyers rely on our industrial screws because we ensure absolute compliance with project datasheets and chemical-mechanical standards.
PMI Chemical Testing
100% Positive Material Identification (PMI) using XRF spectrometers to verify exact alloy element ratios prior to forging.
Precision Thread Gauging
Thread pitch accuracy verified using calibrated Go / No-Go ring gauges to guarantee smooth torque and zero field seizing.
Mechanical & Proof Load
Tensile strength, yield point, elongation, and Rockwell / Brinell hardness tested per ASTM & DIN protocols.
EN 10204 3.1 Certification
Full material traceability supplied with every export lot, linking heat numbers directly to raw material mill certificates.
Seaworthy Packaging & Fast Global Shipping
We understand the importance of damage-free delivery for international supply chains. Screws are individually treated with rust-inhibiting oils, vacuum-sealed in heavy-duty polyethylene bags, boxed in reinforced corrugated cartons, and packed inside ISPM-15 compliant heat-treated wooden crates for safe ocean or air transport.
