Screws & Bolts

Slotted countersunk screws are a type of fastener with a slotted drive and a countersunk (also known as a flat or flush) head. The slotted drive has a single straight slot across the head of the screw, which is designed to be turned using a flathead screwdriver. The countersunk head has an angled shape that allows the screw to sit flush with the surface it is fastened to, making it ideal for applications where a smooth, flush finish is desired.   Material Stainless Steel (A2) Finish Natural Manufacturing Standard DIN 963 Screw Thread Pitch 0.4mm Thread M2 (2mm), Right Hand Thread Countersunk Angle (CA) 90 Degrees (+2/-0) Head Length (H) 1.2mm Maximum Head Diameter (D) 3.8mm Slot Depth (F) 0.6mm Slot Width (A) 0.5mm   For larger quantities or sizes not listed, please email frank@franksfasteners.co.uk and we will be happy to provide you with a quotation.

M3 Socket Countersunk Screws (DIN 7991) in self-colour high tensile steel (10.9) are specific types of screws with particular characteristics: M3: This refers to the metric thread size of the screw. M3 indicates that the diameter of the screw is 3 millimeters. 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.

M3 Socket Countersunk Screws (DIN 7991) in Stainless Steel (A2) are another type of screws with specific characteristics: M3: This is the metric thread size of the screw, indicating a 3-millimeter diameter. Socket: These screws feature a socket (hexagonal) drive, requiring a hex key or Allen wrench for installation and removal. The socket drive design provides a secure and efficient way to apply torque. Countersunk: Countersunk screws have a conical head with a flat top, allowing them to sit flush with the surface when installed, providing a clean and smooth finish. DIN 7991: This refers to the DIN specification that the screws conform to. DIN 7991 specifies the dimensions, tolerances, and other requirements for socket countersunk screws. Stainless Steel (A2): Stainless steel is a corrosion-resistant material, and A2 is a specific grade or alloy within the stainless steel family. In this context: Stainless Steel: Stainless steel is highly resistant to corrosion, making it suitable for a wide range of applications, including those exposed to moisture, humidity, or chemicals. A2: A2 stainless steel, also known as AISI 304, is a popular stainless steel grade. It is known for its excellent corrosion resistance, making it suitable for general-purpose applications. It contains about 18% chromium and 8% nickel, which contribute to its corrosion resistance properties.
