JVS Nut Bolt

HSFG Bolt Manufacturer in India

JVS Nut Bolt, a brand of Oxford International in Ludhiana, manufactures High Strength Friction Grip (HSFG) bolts, nuts and washers for steel bridges, PEB structures, power plants, towers and heavy industrial frames. We are an ISO 9001:2015 certified manufacturer with 45+ years of experience, supplying factory-direct across India.

HSFG (High Strength Friction Grip) bolts are structural fasteners that join steel members through clamping force rather than shear on the bolt shank. When tightened to the specified preload, the connected plates are pressed together so firmly that friction between them carries the load.

This makes HSFG connections the preferred choice where vibration, load reversal or fatigue can loosen ordinary bolts, such as bridges, crane girders and heavy industrial structures.

    Applications of HSFG Bolts

    Friction grip connections keep steel joints tight where vibration, load reversal and fatigue would loosen ordinary bolts. These are the structures our HSFG bolts, nuts and washers go into.

    Most demanding use

    Railway & Highway Bridges

    Girder, truss and splice connections that carry moving traffic every day. Clamping force stops the joint from slipping under repeated loading.

    Vibration, load reversal, fatigue

    PEB & Industrial Sheds

    Portal frame rafter and column connections in warehouses and factories.

    Wind and frame loads

    Power Plants

    Boiler supports, turbine halls and chimney structures.

    Heat cycles, heavy load

    Transmission & Telecom Towers

    Lattice tower leg and bracing joints exposed to constant wind.

    Wind sway, dynamic load

    Crane Girders & Gantries

    Runway beam splices that see repeated lifting and braking loads.

    Repeated lifting loads

    Metro & Flyovers

    Steel viaduct girders and box sections in urban infrastructure.

    Traffic vibration

    Steel Plants & Heavy Engineering

    Process structures, conveyor galleries and equipment frames.

    Heavy loads, shock

    Solar Mounting Structures

    Galvanized frames for ground-mount and rooftop arrays.

    Wind uplift, outdoor exposure

    FAQs

    What does HSFG stand for?

    HSFG stands for High Strength Friction Grip. These bolts are tightened to a high preload so that friction between the connected steel plates carries the load, not the bolt shank.

    Who is a reliable HSFG bolt manufacturer in India?

    JVS Nut Bolt, a brand of Oxford International based in Ludhiana, Punjab, is an ISO 9001:2015 certified manufacturer with 45+ years of experience, supplying HSFG bolts, nuts and washers across India.

    What is the difference between 8.8 and 10.9 HSFG bolts?

    Both are high-strength classes. 8.8 is common in general structural work, while 10.9 gives higher strength for heavily loaded connections.

    What is the difference between HSFG bolts and ordinary bolts?

    HSFG bolts resist load through friction from high clamping force, which gives better slip, vibration and fatigue resistance. Ordinary bolts rely on bearing and shear.

    Can HSFG bolts be reused?

    Generally no. Once tightened to full preload, a bolt may have been stressed beyond its intended range. Follow your project specification.

    Do you supply complete bolt, nut and washer sets?

    Yes, we supply matched sets so preload performance is consistent.

    Do you supply galvanized HSFG bolts?

    Yes, hot-dip galvanized fasteners are part of our range. Coating affects tightening behaviour, so mention your finish when ordering.

    Do you supply HSFG bolts in bulk across India?

    Yes. We handle bulk and project orders from Ludhiana with PAN India delivery.

    How do I get an HSFG bolt quotation?

    Send your size, length, grade, finish, quantity and delivery location via the quote form or WhatsApp, and we will reply with pricing and availability.
