Product Description

Solar Panel Mounting Dowel Screws Hanger Bolt with EPDM Washer & Flange Nuts

Hanger bolts are a type of bolts for special purposes, mainly used for suspending or hoisting various objects, equipment, and structural components, etc.

Carbon Steel: Such as Q235, etc. This material has relatively good strength and toughness, can meet the requirements of most general suspension scenarios, and has a relatively low cost.

304 Stainless Steel: It can adapt to humid, weak acid and alkali environments.

316 Stainless Steel: It is more suitable for highly corrosive environments, such as seaside and chemical plants.

High-Strength Alloy Steel: It can meet the requirements of ultra-high-strength suspension, for example, in some suspension structures of large bridges or the hoisting connection parts of heavy machinery.

Thread Specifications	Coarse Threads: There are M6, M8, M10, etc. For example, the pitch of M6 is 1mm, which is suitable for general suspension scenarios. Fine Threads: Such as M8×1, etc. With a small pitch, it is used for high-precision or high-vibration occasions.
Shank Length Specifications	Ranging from dozens of millimeters to several meters, depending on the height of the suspended object, the thickness of the connecting parts, and the installation space.
Head Shape and Size Specifications	Hexagonal Head: The width across flats of M6 is about 10mm, and that of M10 is about 16mm. The head thickness is 3 - 8mm. Round Head: The diameter ranges from 10mm to more than 30mm, depending on the specification and load-bearing requirements. Square Head: For example, the side length of M8 is about 13mm, with good positioning performance.
Strength Grade Specifications	There are 4.8 grade, 8.8 grade, etc. The 4.8 grade is used for light loads, the 8.8 grade is used for general industry and construction, and the 10.9 grade and 12.9 grade are used for occasions with high-strength requirements.
Surface Treatments	There are galvanizing (electro-galvanizing, hot-dip galvanizing), nickel plating, chromium plating, etc.

Hanger bolts have the advantages of strong stability, wide applicability (covering various materials to cope with different environments and load-bearing ranges), convenient installation (multiple head shapes are conducive to operation), high precision selectivity (coarse and fine threads meet different precision requirements), and strong customizability. They can effectively undertake suspension tasks and adapt to complex and changeable working conditions in multiple fields such as construction, industry, and transportation.
