In high-performance mechanical and industrial systems, leak prevention and component stability are mission-critical. Enter the Brass Sealing Screw—a small but powerful mechanical fastener engineered to offer both fastening strength and a reliable seal. These specialized screws are widely used in applications where environmental sealing is essential, including automotive, electrical, plumbing, and instrumentation sectors.
At Kriloha Ltd., we take pride in delivering premium-grade brass sealing screws that combine durability, corrosion resistance, and a perfect sealing function.
Brass sealing screws are specially designed threaded fasteners made from brass alloy, often integrated with a sealing washer or gasket. Their primary role is to secure components while also preventing leaks, moisture ingress, and contaminants from penetrating joints or enclosures.
These screws are most commonly used in pressurized systems, fluid handling machinery, electronic enclosures, and outdoor mechanical assemblies.
Used in engine parts, fluid reservoirs, and battery compartments, brass sealing screws ensure tight joints that withstand temperature changes and vibrations.
Enclosures and panel boxes require sealing screws to protect sensitive electronics from dust and water, especially in outdoor or industrial setups.
Due to brass’s natural resistance to corrosion, especially in wet conditions, sealing screws are ideal for securing joints in pipelines, pumps, and water meters.
Precision instruments rely on brass sealing screws to maintain calibration and performance in sealed environments.
Sealing screws are used in heat exchangers, air conditioners, and refrigeration units to avoid refrigerant leakage.
All our screws go through strict quality inspection to ensure dimensional accuracy and performance reliability under pressure.
At Kriloha Ltd., we don’t just deliver parts—we deliver confidence. Our advanced machining capabilities and custom order support make us a preferred partner for OEMs and industries across the globe.
A brass sealing screw is a type of fastener made from brass and designed to provide a leak-proof seal, often used with an integrated washer or gasket. It ensures both fastening and protection against fluid, dust, or gas leakage.
Brass sealing screws are widely used in:
• Automotive (for engine and battery compartments)
• Electrical enclosures
• Plumbing and water meters
• HVAC and refrigeration systems
• Instrumentation and control systems
We offer:
• Excellent corrosion resistance
• Non-sparking and non-magnetic properties
• Good thermal and electrical conductivity
• Reliable sealing for harsh environments
They typically come with integrated sealing washers (like rubber or silicone O-rings) or use thread sealants. These elements compress when the screw is tightened, creating a tight, leak-proof seal.
Yes, but it depends on the application. The screw itself is reusable, though the sealing washer or gasket may need replacement if it's deformed or worn after multiple uses.
Yes. Brass is highly resistant to corrosion and weathering, making sealing screws suitable for outdoor applications like electrical boxes, lighting, and HVAC systems.
Yes. They are available in various sizes (typically M2 to M20) and thread types such as metric, UNC, and UNF. Custom dimensions are also available from suppliers like Kriloha Ltd.
Absolutely. Brass is an excellent conductor of electricity and heat, making these screws perfect for electrical enclosures and terminal fittings.
Finishes include natural brass, nickel-plated, chrome-plated, or passivated versions to enhance durability, aesthetics, and resistance to specific environments.
