Grade 2 Titanium Machine Screws

Commercially pure Grade 2 titanium machine screws for corrosion-resistant equipment and compact assemblies. Head style, drive, thread, length, surface condition and inspection are supplied to the specified standard or drawing.

Material: Grade 2 / UNS R50400
Head Styles: Pan, cheese or drawing-specific
Threads: Metric, UNC, UNF or drawing
Documents: MTC, dimensions and thread inspection

Product Detail

Product Introduction

Grade 2 machine screws are chosen where commercially pure titanium corrosion resistance and useful ductility are more important than the higher strength of Ti-6Al-4V. The order must define head, drive, thread, length, material condition, finish and finished-screw acceptance.

Product Specifications

Product	Grade 2 Titanium Machine Screws	Material	Titanium Grade 2 (UNS R50400)
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

Head style: Pan and cheese heads provide different bearing areas and installed profiles; drawing-specific forms can be reviewed.
Drive geometry: Specify cross recess, six-lobe, slot, socket or other drive and use correctly matched tooling.
Joint compatibility: Confirm mating material, thread engagement, preload, temperature, lubrication and galvanic exposure.

Standards and ordering definition: ISO 7045, ISO 1580 and legacy DIN references may define dimensional geometry. They do not automatically establish Grade 2 titanium material or finished-fastener performance; ASTM F468/F468M applies only when expressly specified.

Mechanical Properties – Grade 2 Material Reference

Property	Annealed Grade 2 Material Reference Minimum
Ultimate tensile strength	345 MPa (50 ksi)
0.2% yield strength	275 MPa (40 ksi)
Elongation	20%

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 2 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 2 Titanium Machine Screws?

ISO 7045, ISO 1580 and legacy DIN references may define dimensional geometry. They do not automatically establish Grade 2 titanium material or finished-fastener performance; ASTM F468/F468M applies only when expressly specified.

How are Grade 2 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.
