Cross Countersunk Lock Screw with Anti-Loosing & Anti-Slip Coating and Standard Phillips Countersunk Head for Vibration Proof Fastening

Situo Hardware is a professional manufacturer specializing in cross countersunk lock screws, anti-slip anti-loosing coated screws, vibration-proof flat head fasteners and anti-drop mechanical fixing screws. Our products are widely used in automation equipment, electrical appliances, precision instruments, household equipment and long-term vibration mechanical assembly fields.

This series of Phillips flat head lock screws adopts standard countersunk head design for flush installation without protruding, ensuring compact and neat assembly. The thread is professionally coated with high-quality anti-loosing adhesive. After locking, the glue fills the thread gap and forms a strong locking structure, effectively preventing loosening and falling off caused by long-term equipment vibration and operation. With standard thread precision and stable clamping force, the screws provide dual protection of firm fastening and vibration resistance, suitable for various high-stability industrial assembly scenarios.

• Anti-Loosing & Anti-Slip Coating, Excellent Vibration Resistance: The uniform and high-adhesion thread coating forms a mechanical locking effect after installation. It effectively offsets vibration gaps, prevents screw loosening, sliding and falling off during long-term equipment operation, greatly improving equipment running stability and safety.
• Standard Phillips Countersunk Head for Flush Mounting: The flat countersunk head is completely embedded in the mounting surface after installation, no protrusion, no interference with surrounding parts, suitable for compact and precision assembly environments. The cross groove ensures convenient disassembly and assembly without slipping or collapsing.
• Premium Material with Strong Durability: Optional carbon steel and stainless steel (304/316) materials. Carbon steel features high cost performance and strong fastening force; stainless steel provides excellent rust and corrosion resistance, adapting to humid, outdoor and dusty working conditions. The screws are not easy to slip or break under force.
• Precise Thread Machining & Good Compatibility: Precision thread rolling ensures uniform pitch, burr-free and standard tooth profile. Perfectly matched with standard threaded holes and nuts, the screws lock smoothly with minimal clearance. Combined with anti-loosing coating, it achieves double anti-vibration and anti-loosing effect.
• Flexible Non-Standard Customization: Customizable length, thread pitch, coating range and head specification. Full thread, half thread, lengthened and thickened special specifications are available. We provide exclusive fastening solutions according to equipment vibration frequency and assembly requirements.
• Strict Quality Control & Stable Batch Consistency: Full-process inspection including raw material screening, thread precision testing, coating adhesion test and appearance inspection. All products feature stable anti-loosing performance and high batch interchangeability, suitable for mass production and assembly.

• Vibration-proof fastening for automated equipment and transmission machinery
• Flush mounting locking for electrical equipment, control cabinets and precision instruments
• Anti-slip fixing for household appliances, digital products and precision shell assemblies
• Rust-proof and anti-drop fastening for outdoor and humid environment equipment
• Assembly fixing for mechanical equipment with long-term high-frequency operation
• Precision assembly scenarios requiring flush installation and high stability locking
