DIN935 Hex Slotted Castle Nut Carbon Steel Anti‑Loosening Fastener

DIN935 Hex Slotted Castle Nut Carbon Steel Anti‑Loosening Fastener is a reliable locking fastener manufactured in strict accordance with DIN 935 European industrial standard. It features special slotted hex structure, which allows assemblers to pass cotter pin through reserved holes of matched bolts to achieve mechanical anti‑loosening effect. Unlike ordinary lock nuts that rely on friction, it delivers stable locking performance under long‑term vibration, impact and alternating load. This fastener is widely deployed for heavy‑duty machinery, commercial vehicles, agricultural equipment and transmission system connections.

Raw Material & Production Standards

High‑quality carbon steel SAE1045 is adopted as main raw material for DIN935 Hex Slotted Castle Nut Carbon Steel Anti‑Loosening Fastener, to satisfy grade 8 and grade 10 mechanical property requirements.

Full‑container orders will be loaded onto standard export pallets to avoid collision and extrusion during long‑distance logistics. Our factory supports large‑volume bulk orders, small‑batch stock orders and non‑standard customized size service for global industrial purchasers. Custom packing marks and special packaging solutions can be arranged according to buyer’s requirements. Complete certification documents can be supplied upon buyers’ application.

FAQ

Q1: What accessories must be matched with DIN935 Hex Slotted Castle Nut Carbon Steel Anti‑Loosening Fastener?

A: It must work with slotted bolt with pin hole and supporting cotter pin. Ordinary common bolts without pin hole cannot realize mechanical anti‑loosening function.

Q2: What is the difference between grade 8 and grade10 DIN935 Hex Slotted Castle Nut Carbon Steel Anti‑Loosening Fastener?

A: Grade 10 version adopts higher‑strength heat‑treatment process and bears higher tensile load. Grade 8 version fits general‑load scenarios, grade 10 is recommended for heavy‑load industrial equipment.

Q3: Can DIN935 Hex Slotted Castle Nut Carbon Steel Anti‑Loosening Fastener be used for coastal corrosive environment?

A: Zinc‑plated version is suitable for indoor and mild‑corrosion environment. For coastal high‑salt‑fog working conditions, hot‑dip galvanized surface treatment is suggested to improve anti‑corrosion lifespan.

Q4: Can you provide material test report for DIN935 Hex Slotted Castle Nut Carbon Steel Anti‑Loosening Fastener?

A: Our factory can provide MTR material test report, hardness report and dimension inspection report for each production batch. Please put forward requirements before placing orders.

Q5: What is your standard packing for DIN935 Hex Slotted Castle Nut Carbon Steel Anti‑Loosening Fastener?

A: Standard packing is waterproof inner bag plus export carton. Pallet packing is adopted for full container shipment. Custom logo and shipping marks are available.
