Product Introduction: MS Bolts

“MS Bolt” stands for Mild Steel Bolt. These are types of fasteners made out of mild steel, commonly used in many construction, industrial, mechanical, and structural applications where high strength is not the only requirement but cost, weldability, ductility, and availability matter. Zenith Industries is a manufacturer of MS Bolts, along with other fastening hardware, in Kolkata, West Bengal, Odisha, Bihar, Jharkhand, Chhattisgarh, and Assam. Their bolts are used in foundation works, structural joinery, machinery, etc.

Manufacturing Process (Typical for MS Bolts)

While I don’t have access to the exact in-house process of Zenith Industries beyond what public sources say, here is a generally applicable process for how MS Bolts are manufactured, which likely aligns with their operations:

Step

Description

Raw material procurement

Mild Steel rods / bars are procured, usually of certain carbon content, chemical composition controlled to suit strength, ductility.

Cutting / Shearing

From the bar to required blank length.

Heading / Forging

Forming the bolt head. Cold heading or hot forging depending on size.

Thread rolling (or cutting)

The shank is made threaded via rolling dies (preferred for strength) or cutting taps.

Heat treatment / Hardening & Tempering (if required)

For standard mild-steel bolts, often a normalization or light heat process to relieve stresses. High tensile or special bolts may require quenching and tempering.

Surface finishing / Coating

To protect from rust: options include black oxide, zinc plating, galvanization, sometimes passivation coats.

Quality control

Checking dimensions (length, thread pitch, head size), mechanical properties (tensile strength, yield), hardness, surface finish. Thread gauges and micrometers etc.

Packing & dispatch

Bundling, labeling, packing so that bolts do not get damaged or corroded in transit.

Features & Specifications

Here are typical features and specifications for high quality MS Bolts like those from Zenith Industries:

Feature

Typical Specification / Value

Material

Mild Steel (low carbon steel, e.g. ~0.2% carbon)

Strength grade

Depending on application, grades like 4.6, 4.8, or higher, though if un-graded mild steel then lower strength.

Dimensions

Diameter (e.g. M5, M6, M8, M10, up to large sizes), thread pitch (metric or imperial), length, head style (hex, eye, T-bolt, etc.).

Tolerances

Standard tolerances on thread, diameter, length as per IS / ISO / DIN standards.

Surface finish

As mentioned: plain / black / zinc plated / hot dip galvanized, etc.

Corrosion resistance

Via coating or plating; even mild steel bolts need protection especially if outdoor.

Certification / Standard compliance

May comply with Indian Standards (IS), international standards (ISO, DIN, ASTM) depending upon buyer requirement. Zenith Industries mentions ISO 9001:2000 in company profile.

Benefits / Advantages

Using MS Bolts from a reputable manufacturer like Zenith Industries offers multiple benefits:

  • Cost-effectiveness: Mild steel is cheaper than alloy or stainless steel. For many applications (non-corrosive, non-extremely high stress), MS boltsdeliver adequate performance at lower cost.
  • Availability & variety: Zenith offersa wide range of bolts (different types: foundation, T bolts, welded eye bolts, etc.), which helps matching specific needs.
  • Customizability: Clients can often specify bolt size, thread, lengths, head type, finish etc.
  • Reasonable mechanical properties: Mild steel offers good ductility, moderate strength; bolts can handle shearing, tension loads well under design limits.
  • Ease of fabrication & installation: Mild steel bolts are easier to cut, drill, weld if needed (if uncoated or after removing coating), easier to machine.
  • Good quality control: Since Zenith Industries is ISO 9001 certified, likely they follow documented quality control processes.

Possible Limitations

Just to be realistic:

  • Corrosion: Mild steel rusts if not well protected. So suitable coatings or galvanization needed for outdoor or humid environments.
  • Strength limits: For very high load or critical structural, higher grades/alloy steel bolts may be needed.
  • Precision & finish: For precision engineering applications, MS may not always meet tight tolerances or fatigue requirements.

Technical Chart

Here is a sample technical data chart one might prepare for MS Bolts from Zenith Industries. This is illustrative; actual values depend on client specification, bolt size, and finish.

Property

Typical Value / Range

Tensile Strength

~ 350-550 MPa (depending on grade)

Yield Strength

~ 250-350 MPa

Elongation (in 50 mm)

~ 15-25%

Hardness

~ 120-160 HB (Brinell) for untreated; higher if cold worked or surface hardened

Thread Pitch

Metric coarse / fine (e.g. M8 × 1.25, M10 × 1.5 etc.)

Surface Finish

Zinc plating 5-10 µm, galvanization (HDG), black oxide, plain

Dimensions Tolerance

As per IS/ISO standards (e.g. ±0.15 mm on diameter for small sizes, etc.)

Relevance across Regions: Kolkata, West Bengal, Odisha, Bihar, Jharkhand, Chhattisgarh, Assam

Since Zenith Industries is located in Kolkata, they are well positioned to supply MS Bolts across much of Eastern India, including the states you listed. Some points about regional relevance:

  • Proximity reduces lead time and transport cost for West Bengal, Odisha, Jharkhand, Bihar.
  • For Assam and more remote areas, shipping cost and logistics might matter more; customer may need to negotiate minimum order, better packing.
  • Weather in some states (high humidity, rain) means corrosion protection (coating, quality finish) becomes more important.
