M10x40 Hex Head Bolts, High Strength Steel, Black Hex Bolts, Cap Screws for Metal Construction, Machinery, DIY Class 10.9 DIN933 10mm x 40mm (10 pack)

HEXAGONAL CAP SCREWS: These screws have a solid hexagonal head. They are designed for manufacturing and construction applications. The screws have a hexagonal head without a recess. The sides are evenly spaced, resulting in a hexagonal shape.
USE: Hex head bolts are used for applications requiring higher torque than traditional round head screws—they are less likely to strip. A socket wrench is required.
SUITABLE FOR: Hex head screws are widely used in all kinds of mechanical equipment, electronic products, communication equipment, furniture and equipment, construction, and other production, installation, and maintenance applications.
HIGH-STRENGTH STEEL: Corrosion resistant. Prevents bimetallic corrosion. High-strength steel has more than twice the tensile strength of mild steel. High-strength steel is also known as HT steel. HT Grade 10.9 bolts are generally used in automotive applications and for bolting large forged parts, typically for permanent connections.
DIMENSIONS: Diameter M10, Length 40, Head Height 6.4, Wrench Size 17, Thread 1.5, Class 10.9
