Product description

Compiled from the existing technical description of this product on this site

This sealing anti-loosening multifunction screw integrates a sealing element under the head; the body is a high-strength structural part, and when tightened the seal automatically fills the clearance of the mating face, forming a water- and dust-proof barrier. Fastening, sealing and cushioning locking are combined in one part, which suits holes that must both carry load and seal, and reduces the number of assembly parts and potential leak points.

Technical Features
A sealing element is integrated under the head; tightening seals the joint with no separate gasket neededThe seal is compressed and fills the gap automatically, tolerating a certain flatness deviationAlso acts as a cushion, absorbing part of the vibration energyOne part handles both fastening and sealing, reducing leak points and assembly stepsSeal material and hardness made to drawing
Applications
Battery pack enclosures for new energy vehiclesWaterproof control units and light housingsOutdoor equipment, pumps and valvesMoisture-sensitive areas of precision instruments

FAQ

Material, standards, surface treatment and installation points for this model; the data comes from the specification table on this page and from the national standards cited in the answers.

Q1What material is the sealed anti-loosening multi-function screw (seal material and hardness made to drawing) available in, and what strength level does it reach?

Marked in the specification table on this page: material is high-strength alloy steel. Material certificates and mechanical property test reports can be supplied with the goods; batch acceptance follows the data above.

Q2What are the main features of the sealed anti-loosening multi-function screw (seal material and hardness made to drawing)?

Features listed in this product description: a sealing element is integrated under the head, sealing upon tightening with no separate gasket needed; the seal fills the gap automatically under compression and tolerates a degree of flatness deviation; it also cushions and absorbs part of the vibration energy; fastening and sealing are completed by a single part, reducing leak points and assembly steps.

Q3To which standard is the sealed anti-loosening multi-function screw (seal material and hardness made to drawing) produced and accepted?

Standards marked in the specification table on this page: thread GB/T 196, GB/T 197 (ISO 965-1) 6g; mechanical properties GB/T 3098.1 (ISO 898-1); sealing class IP68 (IEC 60529). Dimensional inspection reports can be supplied with the shipment; batch acceptance follows the standards above and the drawing agreed by both parties.

Q4Which surface treatments are available for the sealed anti-loosening multi-function screw (seal material and hardness made to drawing), and how to choose?

The specification table on this page lists surface treatments: black oxide / zinc plated / zinc-nickel alloy (optional). Different coatings differ in appearance, corrosion resistance and cost; choose according to the service environment and order agreement.

Q5Why does the sealed anti-loosening multi-function screw (seal material and hardness made to drawing) still need an anti-loosening feature?

Most loosening originates from transverse vibration: relative micro-movement of the clamped parts weakens friction in the thread pair and the bolt gradually rotates loose. Locking elements are therefore usually evaluated with transverse vibration test methods (such as DIN 65151), measuring the loss of residual clamp load to quantify locking performance.
