Sealing Screw safeguards applications from extreme weather, moisture, and gas infiltration by eliminating gaps between fasteners and contact surfaces. This protection is accomplished through a rubber O-ring installed beneath the fastener, which creates an effective barrier against contaminants like dirt and water penetration. The compression of the O-ring ensures complete closure of potential entry points, maintaining environmental integrity in the sealed assembly.
Types of Sealing screws
Sealing screws come in various types, each suited to specific applications and designs. Here are some common types of waterproof screws:
Sealing Pan Head Screws
Flat head with built-in gasket/O-ring, compresses surfaces to block water/dust in electronics.
Cap Head O-Ring Seal Screws
Cylindrical head with O-ring, seals under pressure for automotive/machinery.
Countersunk O-Ring Seal Screws
Flush-mounted with O-ring groove, waterproofs marine gear/instruments.
Hex Head O-Ring Seal Bolts
Hex head + flange + O-ring, resists vibration in pipes/heavy equipment.
Cap Head Seal Screws withUnder Head Seal
Pre-coated rubber/nylon layer, instant sealing for outdoor/telecom setups.
These types of sael screws can be further customized in terms of material, thread type, O-Ring，and surface treatment to meet the specific needs of various applications.
Application of Sealing screws
Sealing screws are widely used in scenarios requiring leak-proof, corrosion-resistant, or environmental isolation. Key applications include:
1. Electronics & Electrical Equipment
Applications: Smartphones/laptops, outdoor surveillance systems, telecom base stations.
Function: Block moisture/dust from sensitive circuits (e.g., O-ring screws or nylon-patched screws).
2. Automotive & Transportation
Applications: Engine components, headlights, battery housings, chassis.
Function: Resist oil, heat, and vibration (e.g., flanged screws or cap head O-ring screws).
3. Industrial Machinery
Applications: Hydraulic systems, pipelines, pumps/valves, heavy machinery.
Function: High-pressure sealing and shock resistance (e.g., hex head O-ring bolts or thread-sealed screws).
4. Outdoor & Construction
Applications: Marine decks, outdoor lighting, solar mounts, bridges.
Function: Saltwater/corrosion resistance (e.g., countersunk O-ring screws or stainless steel flanged screws).
5. Medical & Lab Equipment
Applications: Sterile instruments, liquid-handling devices, sealed chambers.
Function: Chemical resistance and airtightness (require biocompatible sealing screws).
