Lock Nuts

Lock Nuts are designed to resist loosening of a threaded joint under specified service conditions. BCUBE supplies applicable locking-nut designs and materials.

Types

Locking designs may include prevailing-torque nuts, all-metal lock nuts and other application-specific locking arrangements.

Mechanical & Thread Requirements

Selection depends on thread size, pitch, material, prevailing-torque requirement, temperature and assembly conditions.

Applications

Machinery, equipment, vibration-prone assemblies, automotive/industrial applications and other specified bolted joints.

Standards

Applicable standards vary by lock-nut design; the exact standard and edition should be confirmed from the project specification.

Quality

Dimensional checks, thread inspection, material documentation and required testing can be arranged.

ASTM A194/A194M — High-Pressure / High-Temperature Nuts

Where the nut is specified for high-pressure or high-temperature service, ASTM A194/A194M is a key material specification covering carbon steel, alloy steel and martensitic/austenitic stainless steel nuts. ASTM currently lists A194/A194M-26 as active. Exact grade/class, size and service requirements must be matched to the governing specification; ASTM states that grade substitutions require purchaser permission.

Manufacturing & Sourcing

BCUBE operates through manufacturing and sourcing capabilities. Requirements can be evaluated from drawing, material, grade, standard, dimensions and quantity.

Certification & Inspection

EN 10204:3.1 material certificates and Indian or international third-party inspection can be supported where required by the order and agreed inspection scope.

Current & Previous Editions

Where a standard has multiple editions, BCUBE will identify the current edition and retain relevant previous editions for project-specific procurement searches. The client's approved drawing, specification and purchase order remain the controlling documents.
