Grade 2 Titanium Countersunk Screws

Commercially pure Grade 2 titanium countersunk screws for flush, corrosion-resistant assemblies. Head angle, drive, thread, length, material condition and inspection requirements are supplied to the specified standard or drawing.

Material: Grade 2 / UNS R50400
Head Styles: Flat or raised countersunk
Threads: Metric, UNC, UNF or drawing
Documents: MTC, dimensional and thread inspection

Product Detail

Product Introduction

Grade 2 countersunk screws combine commercially pure titanium corrosion resistance with a flush or near-flush installed head. Selection must define the head angle and diameter, drive geometry, countersink preparation, thread tolerance, length measurement method and finished-fastener acceptance plan.

Product Specifications

Product	Grade 2 Titanium Countersunk Screws	Material	Titanium Grade 2 (UNS R50400)
Product Form	Flat or raised countersunk screw	Typical Inquiry Range	M2 to M20 typical metric inquiry range; inch and custom sizes by review
Dimensional References	ISO 10642, ISO 7046, legacy DIN 7991 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 geometry: Specify flat or raised countersunk form, nominal head angle and the governing dimensional reference.
Drive selection: Cross recess, six-lobe, hex socket or drawing-specific drives require matched tooling and controlled recess dimensions.
Joint design: Confirm countersink depth, bearing area, mating material, edge distance, preload and galling controls.

Standards and ordering definition: ISO 10642, ISO 7046, DIN 7991 and ASME B18 references may define particular geometries when expressly invoked. The purchase order must separately define Grade 2 / UNS R50400 material, condition, applicable ASTM F468/F468M requirements and inspection.
