Titanium Socket Head Cap Screws & Inner Hexagon Bolts

Titanium socket head cap screws are the cylindrical-head, Allen-driven fastener you'll find on almost every serious build — known also as socket cap screws or inner hexagon bolts. Titansmith machines them from Grade 5 titanium to DIN912, so you get the clean recessed drive with steel-rivalling strength at a fraction of the weight.

One Fastener, Many Names

Titanium socket head cap screws, titanium socket cap screws, titanium socket head screws, titanium cap head screws, titanium inner hexagon bolts — the search terms vary, but they point to one design: a cylindrical head with a recessed hex socket driven by an Allen key.

That recessed drive is what makes the part so useful. It sits flush or counterbores neatly, keeps a clean profile, and lets you torque in tight spaces where an external head won't fit.

Why the Socket Cap Design Wins

The internal hex grips from inside the head, so you can apply high torque without a bulky spanner swinging around the joint. That's why titanium socket head screws dominate machinery, engines, and precision assemblies where access is tight and appearance matters.

Machined to DIN912, our titanium inner hexagon bolts drop straight into applications built around that standard. You get predictable dimensions, a clean counterbore fit, and a head that looks purpose-made rather than adapted.

Grade 5 Strength, Titanium Weight

Every one of our titanium socket cap screws is cut from certified Ti-6Al-4V. That means roughly 40% less weight than a steel equivalent with comparable strength, plus a stable oxide layer that resists rust, salt, and heat.

The recessed hex is strong, but it relies on a clean tool fit. Titanium holds that socket geometry well, so a correctly-sized Allen key seats fully and torques without rounding — provided you use the right size and correct torque values.

Sizes, Standards, and Finishes

We run titanium cap head screws in metric M3 to M14, cut to DIN912 where it applies, with threads that mate cleanly to matching nuts and tapped holes. Choose raw machined titanium or an anodized color.

Need a length or pitch that isn't on the shelf? As the manufacturer, we machine custom titanium socket head cap screws to your drawing rather than pushing a near-enough substitute.

Socket Cap, Button, or Countersunk?

Socket-drive titanium comes in more than one head shape. The standard cap head is tall and cylindrical, giving maximum grip strength and a bold look. It's the default for structural joints where clamping force matters most.

A button head is lower and domed, softer on the eye and useful where clearance is tight but a flush finish isn't needed. A countersunk head sits fully flush in a chamfered hole, ideal for surfaces that must stay smooth.

All three share the same recessed hex drive and the same Grade 5 titanium. Choosing between them is about profile and load, not material — and we machine each so you can spec the right head for every hole.

Frequently Asked Questions

Are socket cap screws and inner hexagon bolts the same thing?

Yes. Titanium socket cap screws and titanium inner hexagon bolts describe one fastener: a cylindrical head with a recessed hex socket. The names differ by region and habit, but the part — an Allen-driven cap screw to DIN912 — is identical on our bench.

What Allen key size do titanium socket head screws use?

Each size uses a specific metric hex key — for example, an M6 cap screw typically takes a 5 mm key. Always use the correct, fully-seated key to avoid rounding the socket. We can confirm the key size for any titanium socket head screws you order.

Do titanium cap head screws meet DIN912?

Our standard titanium cap head screws are machined to DIN912 dimensions, so they match the counterbores and tools built around that standard. If your application needs a different head geometry, we can machine to your specification instead.

Can I get titanium socket cap screws in custom lengths?

We machine custom lengths and pitches alongside the stock range. If the titanium socket cap screws your build needs aren't listed, send the spec and we'll produce them, retail or wholesale.

What's the difference between cap, button, and countersunk socket screws?

Cap heads are tall with the highest grip strength; button heads are low and domed for a softer, lower profile; countersunk heads sit flush in a chamfered hole. All use the same recessed hex drive, so pick by profile and load — we machine each in Grade 5 titanium.
