Surface Treatment: Bright Finish (Bright Pickling/Passivation)
Product Type: Thin Head Hexagon Socket Cylinder Head
Product Description
Product Overview
This product is a thin head hexagon socket cylinder head screw complying with DIN7984 standard, manufactured from A2-70 grade 304 stainless steel, with bright finish (passivation) surface treatment. Its head height is lower than that of standard hexagon socket cylinder head screws. While providing sufficient clamping force, it significantly reduces the protruding height after installation, saving space. It is suitable for thin plate connection or precision equipment assembly that has strict requirements on installation space and needs good corrosion resistance.
Core Advantages
-
Low-Profile Head Design: The thin head structure effectively saves axial installation space, suitable for compact design.
-
Excellent Corrosion Resistance: 304 stainless steel material combined with bright finish treatment provides comprehensive rust protection.
-
Reliable Connection Strength: A2-70 performance grade ensures sufficient mechanical strength and clamping force.
-
Attractive Hexagon Socket Drive: The head is flat, and the hexagon socket drive enables countersunk installation with a clean appearance.
Applicable Industries
-
Precision Instruments and Electronic Equipment: Space-constrained connections inside optical instruments, precision sensors, and high-end consumer electronic products.
-
Electrical Control and Cabinets: Fastening of thin-plate door panels and mounting plates such as switch cabinets, control boxes, and low-voltage electrical appliances to achieve a flat surface.
-
Mechanical Equipment Panel Installation: Connection points that require a flat or slightly countersunk surface, such as machine tool operation panels and equipment housing covers.
-
Medical Devices and Laboratory Equipment: Thin-walled structure connections that require cleanliness and rust resistance, such as medical device housings and laboratory benches.
-
Food and Beverage & Packaging Machinery: Thin-plate fastening that requires rust resistance and easy cleaning, such as food processing equipment, filling line guardrails, and conveyor belt brackets.
-
Furniture and Decorative Hardware: Concealed installation of metal decorative panels in high-end furniture and exhibits, pursuing a flat and attractive appearance.
Warm Tips
-
Due to the thin head design, the bearing area of the head is smaller than that of the standard head. Please pay attention to controlling the torque during installation to avoid head deformation or slipping caused by overloading.
-
It is recommended to use thin washers of the corresponding standard to protect the connected surface and better distribute pressure.
-
The "bright finish" treatment mainly provides corrosion resistance and a bright appearance, but in high chloride ion environments (such as coastal areas, around swimming pools), it is recommended to evaluate its applicability or consult for higher-grade materials.
