Cross Drill Nut

Description

HBS Fasteners manufactures premium Cross Drill Nuts, engineered for high-security mechanical joints. The defining feature of this nut is the precision-drilled hole that passes horizontally through the hexagonal flats. This allows a safety wire or split pin to be passed through the nut and the bolt, physically locking the fastener in place. They are essential for applications where a fastener failure could lead to significant equipment damage or safety risks.

Technical Specifications

• Standard: Manufactured according to DIN 934 or DIN 935 (Castellated) profiles with custom cross-drilling.

• Feature: Single or multiple transverse holes (cross-drilled) for safety wire or cotter pin integration.

• Drive Type: Standard hexagonal profile for easy installation with wrenches and sockets.

• Size Range: Available in standard metric diameters from M6 to M24.

• Threading: High-precision internal threads with accurate pitch control for a secure fit.

Material & Quality Excellence

• Stainless Steel: Available in high-grade Austenitic (A2, A4) for maximum corrosion resistance in outdoor and marine environments.

• Other Materials: Produced in high-tensile Alloy Steel, Mild Steel, and Brass.

• Manufacturing Control: Produced using raw materials from our in-house wire drawing facility. The cross-drilling process is performed using high-precision CNC machinery to ensure perfect hole alignment without compromising the nut’s structural integrity.

• Surface Finishing: Options include Zinc Plating, Nickel Plating, Black Oxide, and Passivation.

Key Application Areas

• Aerospace & Defense: Critical for securing engine components and control linkages where safety wiring is mandatory.

• Automotive Racing: Used in high-performance vehicles for suspension and braking systems to prevent loosening during high-speed vibrations.

• Heavy Machinery: Ideal for vibrating equipment, rotating shafts, and industrial crushers.

• Power Generation: Used in turbines and generators where fasteners are subject to constant thermal expansion and mechanical stress.
