A hexagon nut, often referred to as a hex nut, is a type of fastener with six flat sides and is designed to be used with a bolt or threaded rod to secure objects together. Zinc Plated Steel means that the hexagon nuts are made of steel and have been coated or plated with a layer of zinc. Zinc plating provides corrosion resistance to the nuts and helps prevent them from rusting when exposed to moisture or environmental factors. It also gives them a shiny silver appearance.These hexagon nuts are commonly used in a wide range of applications, including construction, machinery, automotive, and various other industries where fastening and securing components are required. The DIN 934 standard ensures that these nuts meet specific size, thread pitch, and quality requirements, making them reliable and compatible with other standard fasteners.   Material Steel - Grade 8 Finish Zinc Plated Manufacturing Standard DIN 934 For Use With Thread Size M5 (5mm), Right Hand Thread Screw Thread Pitch 0.8mm Nut Thickness (T) 4mm Nut Thickness (T) Tolerance +0/-0.3mm Nut Width A/F (J) 8mm Nut Width A/F (J) Tolerance +0/-0.22mm For larger quantities or sizes not listed, please email frank@franksfasteners.co.uk and we will be happy to provide you with a quotation.

M5 Socket Countersunk Screws (DIN 7991) in self-colour high tensile steel (10.9) are specific types of screws with particular characteristics: M5: This refers to the metric thread size of the screw. M5 indicates that the diameter of the screw is 5 millimetres. Socket: These screws have a socket (hexagonal) drive, which means you'll need a hex key or Allen wrench to install or remove them. The socket drive design provides a more secure and efficient way to apply torque compared to other drive types like slotted or Phillips. Countersunk: Countersunk screws have a conical head with a flat top. They are designed to sit flush with the surface when installed, giving a neat and smooth finish. DIN 7991: This refers to the standard or specification that the screw follows. DIN 7991 is a standard that specifies the dimensions, tolerances, and other requirements for socket countersunk screws. Self Colour: "Self-colour" means that the screws have not undergone any surface finishing treatment like plating or coating. They are made of plain steel and may be susceptible to corrosion, so they are often used in applications where appearance is not a concern, and other corrosion protection methods are employed. High Tensile Steel (10.9): This indicates the strength and material grade of the screws. "High tensile" means that the steel used is strong and can withstand a significant amount of tensile (pulling) force. The "10.9" is a classification that specifies the hardness and strength of the steel. In this case, 10.9 indicates a tensile strength of 1000 N/mm² and a minimum yield strength of 900 N/mm².
