Poonam Industries is a premier manufacturer, wholesale supplier, and global exporter of high-grade Mild Steel (MS) Nuts, Bolts, Washers, and Studs based in Ahmedabad, Gujarat, India. Fasteners serve as the mechanical backbone for modern infrastructure, fluid transmission, agricultural irrigation networks, and industrial machinery. Engineered to meet strict international standards such as DIN, ISO, IS, and BS, our mild steel fastner lineup provides high tensile endurance, precise thread engagement, and reliable resistance to mechanical stress and vibration.
Whether you are anchoring broad-acre agricultural flange manifolds, constructing heavy structural steel frameworks, or assembling underground pipe networks, selecting the correct material grade and protective surface coating is vital. Our complete fastner catalog includes standard hex head bolts, full-thread hex nuts, flat and spring lock washers, double-end stud bolts, and continuously threaded rods manufactured from premium-grade low and medium carbon steel.
Hex bolts are the standard choice for general engineering, structural connections, and pipeline flange jointing. Manufactured strictly to DIN 933 (full thread) and DIN 931 (half thread) specifications, these bolts offer high shear and tensile load limits.
Sizes: M6 to M64 (Quarter-inch to 2.5-inch diameter).
Grades: Grade 4.6 (standard structural) and Grade 8.8 (high-tensile stress applications).
Applications: Bolting pipe flanges, structural beams, agricultural valve assemblies, and pump bases.
Designed to complement our hex bolts and studs, MS hex nuts are precision-tapped according to DIN 934 and IS 1364 standards. The internal metric threading is uniform and burr-free to ensure smooth engagement without galling or cross-threading during high-torque field installation.
Sizes: M6 to M64.
Property Classes: Class 4, Class 8.
Key Advantage: High resistance to thread stripping under heavy hydrostatic and mechanical tightening loads.
Washers play a critical role in distributing clamping loads evenly and preventing joint loosening caused by physical vibration or thermal expansion.
Plain Flat Washers (DIN 125 / IS 2016): Increases the load-bearing surface area under the bolt head or nut, preventing surface deformation on soft flanges or structural plates.
Spring Lock Washers (DIN 127): Applies continuous spring tension against the fastener head to lock the joint securely under dynamic vibration and fluid shock loads.
For pipeline flange connections and subterranean anchor setups where standard head bolts cannot be inserted, double-end studs and continuously threaded tie rods provide a flexible fastening solution.
Configurations: Fully Threaded Studs, Double-End Studs with Center Collar, Custom Anchor Bolts.
Length Range: Cut-to-length options from 50mm up to 3000mm.
Primary Use: Joining double-flanged irrigation valves, sand filters, hydrocyclones, and concrete puddle pipe anchors.
To ensure long operational life in challenging environments—such as open agricultural fields, buried pipeline trenches, and chemical processing plants—we offer specialized surface finishing choices:
Self-Color / Black Oiled: Supplied with a light protective oil film, ideal for indoor machinery assembly or applications receiving immediate painting/coating on site.
Electro Zinc Plated (Galvanized): Features a smooth layer of electro-deposited zinc (blue/white or yellow passivated) to prevent surface oxidation in standard indoor and light outdoor conditions.
Hot-Dip Galvanized (HDG): Processed according to ISO 1461 standards, this thick zinc coating provides heavy-duty rust protection against soil salinity, fertilizers, weather exposure, and continuous moisture.
Agricultural Micro-Irrigation & Mainlines: Used extensively to bolt together glass-reinforced plastic (GFPP) and HDPE flange assemblies, disc filter loops, header manifolds, and pump discharge stations.
Water Supply & Municipal Infrastructure: Essential for joining ductile iron, mild steel, and thermoplastic pipeline flanges in city water distribution and sewage treatment networks.
Structural Engineering & Solar Racking: Provides secure bolting for structural steel trusses, pre-engineered buildings (PEB), transmission towers, and solar panel mounting frameworks.
Machinery & Equipment Assembly: Delivers dependable joint integrity across industrial pumps, compressors, valve bodies, and heavy earth-moving equipment.
ISO 9001:2015 Certified Manufacturing: Every production lot undergoes dimensional tolerance checks, pitch gauge inspection, and tensile strength testing.
Complete System Compatibility: Designed to integrate seamlessly with standard ANSI, DIN, and IS pipe flanges, valves, and industrial equipment.
Custom Fastener Capabilities: Ability to manufacture custom stud lengths, non-standard thread pitches, and special washer dimensions according to client engineering drawings.
PAN India Supply & Direct Global Export: Packaged in heavy-duty seaworthy cartons, bags, and wooden pallets for safe long-distance transport.
Answer: We manufacture mild steel fasteners in Grade 4.6 for general structural and piping needs, as well as high-tensile Grade 8.8 for high-pressure valve bodies and heavy structural loads.
Answer: Hot-Dip Galvanized (HDG) or Yellow Zinc-Plated coatings are strongly recommended. They shield the underlying carbon steel from moisture, soil salinity, acidic liquid fertilizers, and weather exposure.
Answer: Yes. We offer pre-matched fastener kits (one stud bolt with two hex nuts and two flat washers) packaged specifically for quick field installation on pipe flange lines.
Answer: Standard MOQs start at 500 kg for bulk fastener orders or 100 sets for pre-packaged flange bolting kits. Contact our sales team for exact sizing and shipping details.
