Product Detail
Product Introduction
Grade 2 Titanium Low Head Socket Cap Screws reduce head height while retaining an internal-hex drive. The lower head changes socket depth, head strength and allowable installation torque compared with a standard socket head cap screw, so substitution requires verification of clamp load, clearance, bearing stress, thread engagement and service loading.
Product Specifications
| Product | Grade 2 Titanium Low Head Socket Cap Screws | Material | Titanium Grade 2 / UNS R50400 |
|---|---|---|---|
| Product Form | Standard or drawing-specific titanium fastener | Typical Inquiry Range | Metric, inch and custom sizes confirmed at RFQ stage |
| Dimensional References | Expressly invoked standard 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
- Height restriction: Define maximum head projection, counterbore or surrounding clearance and required bearing-face diameter.
- Drive and torque: Confirm socket size, engagement, tightening tool and permitted torque for the selected shallow-head geometry.
- Threaded joint: State thread, tolerance, length, engagement, mating material, preload method, lubrication and reuse expectations.

FAQ
How is a low head screw different from a standard socket head cap screw?
It has a shallower cylindrical head and usually reduced socket engagement. Clearance improves, but head capacity and tightening limits must be reviewed.
Can DIN 7984 steel torque values be used directly for titanium?
No. Installation torque depends on titanium grade, finished-part requirements, thread friction, lubrication, mating material and joint validation.
What dimensions should be inspected?
Head height and diameter, socket dimensions, overall length, thread size and fit, bearing face and any drawing-specific concentricity requirements should be defined.
