Product description

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

The sealing and self-locking multifunctional screw integrates fastening, locking and sealing in one part: the thread is pre-coated with locking adhesive, and a sealing ring is fitted under the head or on the thread section; after tightening, the adhesive layer locks and the compressed sealing ring fills the gap, simultaneously meeting anti-loosening requirements and IP68 sealing, suitable for hole positions in demanding environments.

Technical Features
Pre-applied adhesive locking plus O-ring sealing, dual-function integrationSealing up to IP68, suitable for harsh environmentsOne part replaces multi-piece assemblies, fewer assembly stepsPrecision cold-headed forming with stable thread accuracySeal material and hardness can be made to drawing
Applications
NEV battery packsOutdoor power electronics and EV chargersFluid components such as water pumps and valve bodiesWater-exposed areas of construction machinery

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 multi-function locking screw (precision cold-headed forming, stable thread accuracy) made of? 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.

Q2To which standard is the sealed multi-function locking screw (precision cold-headed forming, stable thread accuracy) produced and inspected?

Standards stated 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); O-rings GB/T 3452.1; ingress protection IP68 (IEC 60529). Dimensional inspection reports can be provided with the goods; batch acceptance is carried out in accordance with the above standards and the drawings agreed by both parties.

Q3What surface treatments are available for the sealed multi-function locking screw (precision cold-headed forming, stable thread accuracy)? 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.

Q4In which applications is the sealed multi-function locking screw (precision cold-headed forming, stable thread accuracy) used?

Typical applications listed in the product description on this page: new energy vehicle battery packs; outdoor power electronics and EV chargers; fluid components such as water pumps and valves; wading areas of construction machinery. Overview: the sealing and self-locking multifunctional screw integrates fastening, locking and sealing in one part: the thread is pre-coated with locking adhesive, and a sealing ring is fitted under the head or on the thread section; after tightening, the adhesive layer locks and the compressed sealing ring fills the gap, simultaneously meeting anti-loosening requirements and IP68 sealing,

Q5What exactly does the IP68 rating marked for the sealed multi-function locking screw (precision cold-headed forming, stable thread accuracy) mean?

According to IEC 60529: the first digit 6 means complete protection against dust; the second digit 8 means continuous immersion in water without ingress under conditions agreed between the manufacturer and the user. There is no uniform fixed water depth or duration for rating 8; the test conditions agreed by both parties and measured results govern. (Applies to this model “Sealing and self-locking multifunctional screw (precision cold heading, stable thread accuracy)”.)
