Baks mushroom-head screw with serrated nut SGKFM10x20PV for photovoltaic structures

Baks mushroom-head screw with serrated nut SGKFM10x20PV is a fastening set engineered for photovoltaic structures. The set contains a mushroom-head screw with a countersunk-style profile and a matching serrated nut sized for 10x20 fastening points. It is intended for secure clamping in solar panel frames and mounting systems where vibration resistance and reliable joint integrity are required.

Advantages

The mushroom-head geometry provides a larger bearing surface that distributes load evenly and reduces the risk of material damage at the contact area. The serrated nut features radial serrations that bite into the mating surface to resist loosening caused by vibration and thermal cycling. Materials and dimensions are selected for compatibility with standard photovoltaic frame profiles and common mounting rails, enabling straightforward installation with typical power-tool or hand-tool setups.

Suitable for

• Fastening solar panel frames to mounting rails and substructures
• Joining photovoltaic mounting components subject to vibration
• Securing clamps, brackets and mid-clamps in PV arrays
• Applications that require a low-profile mushroom/countersunk head with anti-loosening nut

Key specifications

• Screw head type: mushroom/countersunk-style
• Screw size: 10 x 20 (nominal thread/length designation)
• Nutr serration: radial serrated locking surface to reduce self-loosening
• Intended use: fastening for photovoltaic frames and mounting systems
• Compatibility: designed to work with common PV profiles and mounting rails

How to use

Position the screw through the component or clamp and engage the serrated nut on the opposite side. Tighten using an appropriate driver or socket until the nut serrations fully contact the mating surface and the joint achieves required clamping force. Avoid over-torquing; apply torque values recommended for the materials and thicknesses being joined to prevent deformation of frames or fastener damage. For best results, ensure mating surfaces are clean and free of debris before assembly.

Usage recommendations

Use the Baks SGKFM10x20PV set in PV installations where vibration resistance and secure clamping are priorities. Verify material compatibility and appropriate torque settings for the specific frame and rail materials. Periodically inspect installed joints as part of routine PV system maintenance to confirm tightness and integrity.
