Grade 5 Titanium Flange Nuts

High-strength Ti-6Al-4V flange nuts for lightweight joints requiring an integrated bearing flange. Plain, serrated and drawing-specific configurations are supplied by thread, dimensions and acceptance requirements.

Material: Grade 5 / Ti-6Al-4V / UNS R56400
Types: Plain, serrated or drawing-specific
Threads: Metric, UNC, UNF or drawing
Documents: MTC, traceability and dimensional report

Product Detail

Product Introduction

Grade 5 flange nuts combine a Ti-6Al-4V hex nut body with an integrated flange that distributes bearing load. The joint specification must define flange form, mating surface, thread tolerance, strength acceptance, lubrication, installation method and permitted reuse.

Product Specifications

Product	Grade 5 Titanium Flange Nuts	Material	Titanium Grade 5 (Ti-6Al-4V, UNS R56400)
Product Form	Plain, serrated or drawing-specific flange nut	Typical Inquiry Range	M3 to M20 typical inquiry range; inch and custom sizes by review
Dimensional References	ISO 4161, DIN 6923, 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

Plain flange: Provides a wider bearing surface without relying on serrations for rotational resistance.
Serrated flange: Requires compatibility review for the mating surface, coating, reuse and permitted surface marking.
Joint definition: Specify mating bolt material, property requirements, bearing surface, lubrication and torque procedure.

Standards and ordering definition: DIN 6923, ISO 4161 and ASME B18 references may define dimensional geometry. The order must separately establish Grade 5 / Ti-6Al-4V condition and applicable ASTM F467/F467M finished-nut requirements.
