Apollo Steel Industries manufactures a complete range of industrial fasteners — Hex Bolts, Stud Bolts, U-Bolts, Washers and Anchor Fasteners — in Stainless Steel, Alloy Steel, Duplex, Super Duplex and High-Nickel Alloys. We also offer specialized PTFE Coated and Xylan Coated fasteners engineered for anti-corrosive, anti-galling and high-friction-resistant performance in the harshest industrial environments. Every batch is manufactured under strict quality control with complete material and dimensional traceability.
Precision-machined hexagonal bolts and nuts for structural, piping and general engineering assembly. Manufactured in Stainless Steel, Carbon Steel and Alloy Steel with full and heavy series options, suited for high-load and vibration-prone applications.
Full-thread and double-end stud bolts supplied with matching heavy hex nuts for flanged pipe joints and pressure-vessel connections. Available in continuous thread and tap-end configurations for critical, leak-free service.
U-shaped fasteners used for clamping and supporting pipelines, tubes and round structural members. Manufactured to precise bend radii with rolled or cut threads and supplied with matching plates and nuts.
Flat, spring and belleville washers manufactured for even load distribution and vibration resistance in bolted joints. Precision-punched to tight thickness and flatness tolerances.
Wedge Anchors and V-Anchors engineered for secure base-fixing of heavy machinery, structural steel and refractory linings, delivering reliable holding strength in concrete and masonry substrates.
Socket head cap screws with a hexagonal internal drive, machined for high-strength fastening in confined spaces and precision assemblies. Manufactured with close tolerance heads for a clean, low-profile finish.
Split-ring spring washers manufactured to maintain bolt tension and prevent loosening under vibration and cyclic loading in structural and piping joints.
Fasteners coated with Polytetrafluoroethylene (PTFE) to provide excellent chemical resistance, low friction and anti-galling performance. Ideal for fasteners exposed to corrosive chemicals, high humidity and saline environments.
Xylan is a fluoropolymer coating applied over fasteners for superior corrosion protection, torque-tension control and galling resistance, commonly specified for offshore, oil & gas and marine fastening applications.
