India's fastest-growing industries, railways, automotive, solar energy, heavy engineering, construction, and mining, have one thing in common: they demand fastening solutions that go far beyond the commodity bolt and nut. They need engineered fasteners, precisely designed installation systems, and the application engineering expertise to specify the right solution for every joint.
Avlock India has been built to serve exactly this need. As a leading Indian fastener manufacturer and distributor of speciality fasteners and fastening systems, Avlock offers a comprehensive product range from blind rivets and rivet nuts to lockbolts and structural fasteners supported by technical expertise, matched installation tools, and application-specific engineering guidance.
This article provides an overview of Avlock's core product categories and the industrial applications each serves.
Avlock's lockbolt systems are two-piece, mechanically locked fasteners consisting of a high-strength pin and a swaged collar. They are designed for applications where conventional bolt joints would be inadequate, where vibration, dynamic loading, or safety-critical structural performance demands a joint that cannot loosen.
Key Performance Characteristics: Permanent mechanical interlock cannot loosen under vibration. Controlled, repeatable clamp load not torque-dependent. Fast installation with matched pneumatic or hydraulic tools. Simple visual inspection of the pintail removal confirms installation. Available in multiple diameters, grip lengths, and material specifications.

Avlock Advantage: Lockbolts reduce lifetime maintenance costs by eliminating retorquing requirements across large joint-count structural assemblies.
Avlock's blind rivet range covers the full spectrum of industrial blind fastening applications from standard open-end blind rivets for general assembly to structural blind fasteners for load-bearing joints requiring high shear and tensile performance.
Blind rivets are installed from one side only, making them essential in assemblies where back-face access is restricted or impossible: automotive body panels, solar frame assemblies, rail coach bodies, sheet metal enclosures, and construction cladding systems.

Avlock's rivet nut (blind nut / threaded insert) range enables engineers to create permanent, load-bearing internal threads in thin sheet metal, hollow sections, aluminium extrusions, and composite panels without welding and with only front-face installation access.
Rivet nuts are installed in a pre-drilled hole; the installation tool deforms the body behind the panel to create a secure anchor. The resulting threaded insert accepts standard metric bolts and supports repeated assembly and disassembly.

Thread sizes: M4 through M16 standard
Materials: Steel, Stainless Steel, Aluminium, Brass
Beyond the core blind fastener categories, Avlock supplies a range of speciality fasteners engineered for specific performance requirements across industrial sectors. This includes structural blind bolts for high-load steel assemblies, tension control bolt systems for structural steel construction, corrosion-resistant coated fastener systems for outdoor and marine environments, and application-specific fastener solutions developed in partnership with OEM and project customers.
An engineered fastener delivers its designed performance only when installed correctly with the right tool. Avlock supplies a full range of installation tools matched to its fastener systems from manual hand tools for low-volume and maintenance applications to high-cycle pneumatic and battery-powered tools for production assembly lines.
Matched installation tools ensure correct fastener deformation, consistent clamp load, and repeatable installation quality across production runs. Avlock's technical team can advise on tool selection, calibration, and maintenance for any fastening application.
