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 M6, length 80 mm, thread M6, pitch 1 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. Use compatible high tensile nuts and washers so the mating part does not become the weak point.\u003c\/p\u003e\u003ch3\u003eFinish \u0026amp; Corrosion Protection\u003c\/h3\u003e\u003cp\u003ePlain finish fasteners have no protective plated coating and are best used indoors, in oiled assemblies, in painted structures or where corrosion exposure is controlled.\u003c\/p\u003e\u003ch3\u003eTypical Uses\u003c\/h3\u003e\u003cp\u003eDIN 933 set screws are commonly used in machinery, fabricated steelwork, brackets, frames, maintenance work and general engineering where a fully threaded hexagon head fastener is preferred.\u003c\/p\u003e\u003ch3\u003eTechnical Tips\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eUse DIN 933 where full thread engagement is required.\u003c\/li\u003e\n\u003cli\u003eFor bolted joints, use a matching nut and washer of the same thread size and suitable strength class.\u003c\/li\u003e\n\u003cli\u003eFor Grade 8.8, 10.9 or 12.9 parts, use correctly rated mating nuts and washers.\u003c\/li\u003e\n\u003cli\u003eTorque values vary by diameter, pitch, finish and lubrication; confirm the correct torque for critical assemblies.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSelection Advice\u003c\/h3\u003e\u003cp\u003eChoose DIN 933 when a fully threaded hexagon head fastener is required.
