Grade 5 Titanium Machine Screws

High-strength Ti-6Al-4V machine screws for compact, lightweight aerospace, marine and industrial assemblies. Head style, drive, thread, length, material condition and inspection are supplied to the specified standard or drawing.

Material: Grade 5 / Ti-6Al-4V / UNS R56400
Head Styles: Pan, cheese or drawing-specific
Drive & Thread: Specified drive; metric or inch
Documents: MTC, dimensional and thread inspection

Product Detail

Product Introduction

Grade 5 machine screws provide a higher strength-to-weight ratio than commercially pure titanium fasteners. They are ordered by a complete definition of material condition, head and drive geometry, thread tolerance, length, finish and finished-fastener acceptance requirements.

Product Specifications

Product	Grade 5 Titanium Machine Screws	Material	Titanium Grade 5 (Ti-6Al-4V, UNS R56400)
Product Form	Pan, cheese or drawing-specific machine screw	Typical Inquiry Range	M2 to M12 typical inquiry range; inch and custom sizes by review
Dimensional References	ISO 7045, ISO 1580, 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

Pan head: Provides a broad bearing surface for covers, instruments and equipment panels.
Cheese head: Offers a cylindrical profile where head diameter and tool access are controlled.
Drive selection: Cross recess, six-lobe, slotted and drawing-specific drives require correctly matched tooling and controlled recess dimensions.

Standards and ordering definition: ISO 7045, ISO 1580 and legacy DIN references may define dimensional geometry. They do not automatically establish Grade 5 titanium material properties. ASTM F468/F468M requirements are applied only when expressly specified and applicable to the ordered screw.

Mechanical Properties – Grade 5 Material Reference

Property	Annealed Grade 5 Material Reference Minimum
Ultimate tensile strength	895 MPa (130 ksi)
0.2% yield strength	828 MPa (120 ksi)
Elongation	10%
Reduction of area	25%

Material values do not automatically establish finished-fastener loadability. Finished-part acceptance depends on geometry, manufacturing route, condition and the expressly invoked fastener specification or drawing.

FAQ

What information is required to quote Grade 5 Titanium Machine Screws?

Provide the titanium grade, product form, dimensional standard or drawing, thread or critical dimensions, quantity, surface treatment, mating parts, service conditions and required inspection documents.

Which standards apply to Grade 5 Titanium Machine Screws?

ISO 7045, ISO 1580 and legacy DIN references may define dimensional geometry. They do not automatically establish Grade 5 titanium material properties. ASTM F468/F468M requirements are applied only when expressly specified and applicable to the ordered screw.

How are Grade 5 Titanium Machine Screws inspected?

Available controls include MTC review, head and recess measurement, overall and threaded length checks, GO/NO-GO thread gauging, visual examination, specified mechanical tests and heat/lot traceability.
