DIN7991 Hex Socket Countersunk Head Bolts

Bolts are threaded fasteners with an external male thread and are often confused with screws. A hex cap screw, specifically, is a type of cap screw with a hexagonal head that can be driven by a wrench. ASME B18.2.1 compliant hex cap screws have tighter tolerances than standard hex bolts, ensuring they fit properly where a hex bolt might not. **Product Name:** DIN7991 Hex Socket Countersunk Head Bolts **Standards:** DIN, ASTM/ANSI, JIS, EN, ISO, AS, GB **Materials:** Stainless Steel (SS201, SS303, SS304, SS316, SS316L, SS904L, F593), Carbon Steel, High Strength Steel **Steel Grades:** DIN: 4.6, 4.8, 5.6, 5.8, 8.8, 10.9, 12.9; SAE: 2, 5, 8; ASTM: 307A, 307B, A325, A394, A490, A449 **Finishing Options:** Zinc (Yellow, White, Blue, Black), Hot Dip Galvanized (HDG), Black Oxide, Geomet, Dacromet, Anodization, Nickel Plated, Zinc-Nickel Plated **Production Process:** Cold Forging (M2-M24), Hot Forging (M24-M100), Machining & CNC for Customized Fasteners **Custom Lead Time:** 15-30 days (busy season), 10-15 days (off-season) **Stock Products:** DIN 6923 4.8 Grade, GB5783 and GB5782 8.8 & 10.9 Grade, All DIN Standard Stainless Steel Bolts **Free Samples:** Available for standard fasteners **For more information, visit:** www.hainafastener.com We offer a wide range of high-quality bolts designed to meet international standards.

Round High Pressure Filter Press

The circular Filter Plate Filter Press adopts a hydraulic device as the power mechanism for pressing and loosening the filter plate. The filter plate is circular and made of high-strength and high-toughness polyethylene material with high compressive strength. The filter chamber adopts a linear seal with excellent sealing performance. Well, high pressure. It is mainly used for high-pressure filtration such as clay, porcelain clay, and petroleum dewaxing.

The ultra-high pressure circular filter press is divided into eight main parts, the cylinder base, the fixed plate, the polymer polypropylene filter plate and the guide rod, the intermediate support and the pushing plate, the oil cylinder and the hydraulic station. The circular filter press has a fast processing speed.

Ultra-high pressure circular filter press function introduction:
The ultra-high pressure circular filter press uses high-pressure filter pressing to quickly dehydrate the materials to be filtered and press them into mud cakes. The general pressing pressure can reach 30 kg per square centimeter, and the pressure can be as high as 2 Pa. The temperature of the filtered sludge is basically around 35 degrees. Therefore, the ultra-high pressure circular filter press is not suitable for high-temperature materials. The time of each filtration cycle is between 1.5 hours and half an hour. The moisture content of the mud cake filtered by the filter can be as low as 18%, which can be directly recycled as recycling resources, or can be directly used in the vacuum mud refining machine for mud refining.
