The standard covers the dimensional form of the head, thread and length so the fastener can be selected consistently by diameter, thread and overall length. The fully threaded design is useful where thread engagement is required along the full length of the fastener, or where the screw is installed into a tapped hole rather than used with a nut.\u003c\/p\u003e\u003cp\u003eThis selected size is specified with diameter M5, length 8 mm, thread M5, pitch 0.8 mm.\u003c\/p\u003e\u003cp\u003eSold in multiples of '100 pieces. 1 Box = '100 pieces.\u003c\/p\u003e\u003ch3\u003eMaterial, Grade \u0026amp; Strength\u003c\/h3\u003e\u003cp\u003eGrade 8.8 is a high tensile carbon-alloy steel property class with a nominal ultimate tensile strength of approximately 800 MPa and a yield strength of approximately 640 MPa. It is widely used for engineering, structural and machinery joints requiring higher clamp load than ordinary mild steel fasteners. Torque must be selected from a recognised torque chart using the actual diameter, pitch, finish and lubrication condition.
