Finishes such as passivation, hot dip galvanized, zinc plated, Dacromet-type, Geomet-type, and other coatings are available upon request.
Quick Specs
What Buyers Should Know Before Sourcing Solar Panel Bolts and Nuts
Solar panel bolts and nuts must match rail profile, clamp thickness, module frame, roof structure, wind load, corrosion exposure, and installation sequence. Stainless steel bolt-nut-washer sets are common for exposed clamp positions, while galvanized or zinc flake coated carbon steel may be used for ground mounting brackets and base plates. For assembly planning, review bolt nut washer sets for solar mounting systems.
Buyers should confirm whether nuts are standard hex nuts, flange nuts, lock nuts, T nuts, or channel nuts. Washer selection also matters because flat washers, spring washers, bonded washers, and EPDM washers serve different functions in PV installations.

Material and Grade Explanation
Stainless steel 304 and 316 are widely used for solar panel bolts and nuts because PV systems face rain, humidity, temperature changes, and long outdoor exposure. A2-70 and A4-70 bolt and nut sets are common for clamps, rail connections, and exposed bracket assemblies.
Carbon steel and alloy steel fasteners can be used for ground structures, base plates, and support frames when strength and coating protection are balanced. Buyers comparing stainless and galvanized options can review stainless steel vs galvanized anchor bolts before confirming material.
Surface Finish Selection Guide
Passivated Stainless Steel
Passivated stainless steel bolts and nuts are common for exposed PV rail and clamp positions. They provide clean appearance and practical corrosion resistance for long outdoor service.
Hot Dip Galvanized
Hot dip galvanized bolts and nuts are often used for ground mounting structures, support frames, and base plate assemblies. Thread fit should be checked after coating.
Zinc Plated
Zinc plated parts may be suitable for sheltered or less exposed solar hardware. White zinc and yellow zinc can be supplied according to order requirement.
Dacromet and Geomet
Zinc flake coatings can be considered when higher corrosion resistance is required, especially for outdoor bracket systems and selected high-strength fasteners.
Corrosion Comparison
PV systems often involve stainless steel, galvanized steel, and aluminum parts. Compare finish behavior with the corrosion resistance comparison.
Custom Finish
PTFE, black oxide, nickel, or other coatings can be reviewed for special equipment or bracket needs, but outdoor exposure should be defined clearly.
Manufacturing and Quality Control
Production can include raw material inspection, cold heading, machining, thread rolling, heat treatment when required, surface preparation, passivation or coating, final inspection, and export packing. For solar panel bolt and nut sets, dimensional consistency, thread fit, washer matching, coating coverage, and label accuracy help reduce site delays.
XZ Fastener can arrange dimensional inspection, thread pitch checks, go/no-go gauges, hardness, tensile performance, coating thickness, salt spray testing, visual checks, and packaging verification. Buyers can review the fastener quality control process before defining inspection requirements.
Control Points for PV Bolt and Nut Sets
- Confirm clamp, rail, bracket, roof hook, base plate, and anchor positions.
- Match bolt material, nut material, washer type, and rail material to reduce corrosion risk.
- Specify thread length, clamp range, nut style, and washer dimensions.
- Confirm coating thickness, salt spray requirement, and thread fit after coating.
- Use small boxes, labels, or kits to simplify installation and site receiving.
