Knurled TC4 titanium socket head screws combine a fully threaded shank, internal hex drive and straight-knurled cylindrical head for high-strength, weight-conscious assemblies. The photographs show natural-finish TC4 titanium alloy screws from actual product samples.
Dimensions, thread pitch, head geometry, tolerances, material documentation and packaging are confirmed for each quotation. No size, standard or mechanical value is inferred from the photographs.
Key Features
- TC4 titanium alloy: used where a favorable strength-to-weight balance and corrosion resistance are important.
- Internal hex drive: supports compact wrench-driven installation with a matching hex tool.
- Fully threaded shank: provides thread engagement along the available length defined by the order specification.
- Straight-knurled head: creates a distinctive textured cylindrical surface for identification and handling.
- Natural metallic finish: supplied without a decorative coating unless another approved treatment is requested.

How to Specify Knurled TC4 Titanium Socket Head Screws
An accurate inquiry should state the nominal diameter, thread pitch, under-head length, head diameter and height, socket size, quantity and delivery destination. If a published standard applies, identify the exact document and revision. For a custom component, send a dimensioned drawing that clearly identifies the threaded length, head knurl and all critical tolerances.
- Material: state TC4 and the applicable material specification or certificate requirement.
- Thread: provide diameter, pitch, tolerance class and the required full-thread length.
- Head: confirm cylindrical head dimensions, internal hex size and straight-knurl requirement.
- Surface: specify natural finish, cleaning, polishing, passivation or another approved process.
- Quality: list critical dimensions, thread-gauge checks, inspection sampling and required records.
- Commercial details: include quantity, packaging, labeling and delivery schedule.
Material, Joint and Quality Notes
TC4 is a titanium alloy designation, but the governing material standard must be shown on the request because chemical, mechanical and documentation requirements can differ by market. Material equivalence is not assumed from the grade name alone.
Selection also depends on the mating material, service environment, temperature, load and tightening method. Titanium fasteners may require application-specific assembly practices. The quotation can define dimensional inspection, thread checks, material documents, surface condition and export packaging against the agreed specification.
Ordering Details That Reduce Delays
Include the intended application, mating component, quantity, sample requirement, delivery destination and any inspection documents with the first inquiry. A drawing, bill of materials or spreadsheet can be emailed after the contact form is submitted. Clear revision control is important: mark the current drawing revision and identify any dimensions that differ from a referenced standard. Also state the required packing count, label format and traceability information so these items can be reviewed before pricing.

Frequently Asked Questions
Can the dimensions and full-thread length be customized?
Yes. Send the diameter, length, pitch, tolerances and drawing. Manufacturability is confirmed before quotation.
Can the straight knurl on the head be controlled?
Yes. Show the required knurl pattern, head dimensions and acceptance criteria on the drawing when these details are critical.
Can inspection and material documents be supplied?
List the required certificate, inspection plan and report format before ordering so they can be included in the quotation.
Are samples available?
Sample availability depends on the confirmed specification and current production arrangement. Include the delivery country with the request.
