Allen bolt M8x25

M8 x 25 Allen screw is widely used in the construction of mounting structures for photovoltaic panels. The allen head screw is one of the most frequently purchased products in the store.

Specifications

The hexagonal socket head screw is made of A2 stainless steel, which is resistant to weather conditions. The screw's socket is prepared for a 6mm allen key. The allen screw has a metric thread, with a length of 25 mm

Purpose

The main use of the allen screw in photovoltaic installations is to fasten the center and end clamps connecting solar panels to the mounting structure. The Allen screw is used in conjunction with an M8 sliding key (with a ball or square), which is inserted into an aluminum rail or trapezoidal bridge, depending on the type of sheathing. The length of the allen bolt is selected depending on the height of the photovoltaic panel frame - the bolt should be 10 mm shorter. A significant number of panels have a 35 mm thick frame, so the most common choice is a 25 mm long screw.
