Grade 5 Titanium Lock Nuts

High-strength Ti-6Al-4V prevailing-torque lock nuts for lightweight joints requiring resistance to loosening. Nylon-insert and all-metal configurations are supplied by thread, locking performance and service conditions.

Material: Grade 5 / Ti-6Al-4V / UNS R56400
Locking Type: Nylon insert or all-metal
Threads: Metric, UNC, UNF or drawing
Documents: MTC, traceability and torque report

Product Detail

Product Introduction

Grade 5 lock nuts combine a Ti-6Al-4V nut body with a specified prevailing-torque feature. Selection must match locking form to service temperature, chemicals, mating fastener, lubricant, installation procedure, proof-load requirements and permitted reuse cycles.

Product Specifications

Product	Grade 5 Titanium Lock Nuts	Material	Titanium Grade 5 (Ti-6Al-4V, UNS R56400)
Product Form	Nylon-insert or all-metal prevailing-torque lock nut	Typical Inquiry Range	M3 to M24 typical inquiry range; UNC, UNF and custom sizes by review
Dimensional References	ISO 7040, ISO 7042, DIN, ASME/ANSI or approved drawing	Threads / Dimensions	Metric coarse or fine, UNC, UNF or drawing-specific as applicable
Surface	Machined and cleaned; lubricant, anti-galling treatment or coating by agreement	Documents	MTC, heat/lot traceability and dimensional inspection report
Inspection	Dimensions, thread gauging, surface and agreed functional or mechanical tests	Supply Basis	Approved purchase order, invoked standard and drawing

Typical inquiry ranges are not a stock guarantee. Final manufacturability, tolerances and test requirements are confirmed against the complete RFQ.

Selection and Configuration

Nylon-insert form: Use only where the approved insert material remains compatible with temperature, chemicals, moisture and maintenance life.
All-metal form: Removes the polymer insert but requires validation of prevailing torque, relaxation and galling risk.
Mating joint: Specify bolt grade, thread tolerance, lubrication and the required prevailing-torque test sequence.

Standards and ordering definition: ISO 7040, ISO 7042, DIN and ASME B18 references may define particular forms when expressly invoked. The order must separately establish Grade 5 condition and applicable ASTM F467/F467M finished-nut requirements.
