Professional Machinery Equipment Spare Parts Manufacturer for Global Industrial Buyers

This photovoltaic T-Head Bolt, specially manufactured by YS STEEL Factory, is a dedicated fastener specifically designed for photovoltaic aluminum profiles' T-slots. It is made of high-quality carbon steel through forging and is available in two strength levels: 4.8 and 8.8. It undergoes overall hot-dip galvanizing treatment. The unique T-shaped end can be directly slid into the aluminum profile slot without needing to be inserted from the end of the profile, allowing for free adjustment of the installation position.

When manufacturing this Hexagon socket bolt, the YS STEEL manufacturer uses high-quality carbon steel for a single cold forging process, offering multiple strength grades such as 4.8, 8.8, and 10.9. Two surface treatment options are available: blackening or hot-dip galvanizing. The bolt head features a rolling pattern and is paired with a precisely formed internal hexagonal hole, allowing for precise application of locking torque using an internal hexagonal wrench. The cylindrical head structure supports blind hole installation and can be inserted into pre-drilled countersunk holes without protruding and interfering with surrounding components, making it suitable for compact assembly points.

The Bolt and Nut produced by YS STEEL's suppliers are complete sets of fastening components for outdoor engineering. They consist of hexagonal bolts, nuts, flat washers and spring washers. The products are cold-drawn forged from carbon steel and come in various strength grades such as 4.8, 8.8, and 10.9. They are treated with overall hot-dip galvanizing, and the threads are specially rolled to reserve coating gaps to reduce the risk of locking. The complete sets of components are pre-matched and can be assembled directly upon opening the box, suitable for projects such as photovoltaic supports, steel structures, and greenhouse sheds that are exposed to the outdoors for a long time and subjected to wind vibration loads.

YS STEEL's high-quality hot-dip galvanized Flat washer is the fundamental pressure-bearing component in the bolt connection system. It is made from high-quality carbon steel through precise stamping and conforms to the GB/T97.1 standard. The washer expands the contact area between the bolt and the component, dispersing the concentrated pressure generated during tightening and protecting the substrate surface from being crushed or damaged.

The spring washers supplied by YS STEEL are specialized engineering elastic anti-loosening fasteners. They are made of spring steel and are accompanied by a thermal treatment process. The open structure continuously provides axial elastic preload after the bolt is tightened, counteracting the torque attenuation caused by alternating loads and wind vibrations.

The high-strength Lock nut supplied by YS STEEL manufacturers are specialized locking fasteners designed for outdoor vibration conditions. Unlike ordinary flat head nuts, they rely on an exclusive self-locking thread interlocking structure, which can generate a constant thread locking resistance under continuous alternating loads and wind-induced vibrations. This effectively eliminates the problems of nut loosening, slippage, and detachment from their original position.
