M8x40 Hex Head Bolts, Metric Hexagon Bolts, Black, High Tensile Cap Screws Suitable for Metal Construction Work, Automotive Machinery, DIY, HT Steel Class 10.9 DIN933 8mm x 40mm (Pack of 10)

• HEX CAP SCREWS: Screws have a solid hexagonal head. Screws are designed for manufacturing and construction applications. Screws have six-sided head without a recess. The sides are spread evenly apart, resulting in a hexagonal shape.
• USABILITY: Hex Cap Bolts are used for applications requiring greater torque than that of traditional screws with a circular head - Less likely to strip. Socket wrench needed.
• HEX SCREWS SUITABLE FOR: Hexagon screws are widely used in all kinds of mechanical equipment, electronic products, communication equipment, furniture and equipment, construction and other production, installation and maintenance.
• HIGH TENSILE STEEL: Corrosion resistant. Prevents from bimetallic corrosion, High tensile steel more than twice the tensile strength of mild steel. High tensile steel is also called as HT Steel. HT Grade 10.9 bolts are typically used in automotive applications and for bolting large, forged parts,generally used for permanent connections.
• DIMENSIONS: Diameter M8, Length 40, Head height 5,3, Wrench 13, Thread 1,25, Class 10.9

Hex Cap Screws Benefits of Hex Cap Screws With their hexagonal shape, hex cap screws allow for greater torque than that of traditional screws with a circular head. You can’t install or remove them using a standard screwdriver bit like a flat head or Philip’s head. Rather, you’ll have to use a ratchet and socket combination. Also known simply as a socket wrench, it allows you to fit the socket bit over the head of the hex cap screw. Once positioned, you can turn the socket wrench to install or remove the hex cap screw. The socket wrench will grip all six sides of the head so that you create more torque. Hex cap screws are also less likely to strip than their traditional counterparts. The head of a traditional screw may strip when you install or remove it. When the bit is placed inside the head’s drive recess, it may damage the screw during installation or removal. Hex cap screws distribute this turning force across all six sides so that stripping is less likely to occur. Specifications: Head Type: Hexagonal Material: High tensile steel Size: M8x40
