Titanium Socket Head Screws


Fully Threaded	Partially Threaded

Lightweight like aluminum, more corrosion resistant than stainless steel. The deep, six-point socket keeps hex keys from slipping out and damaging the drive on these screws.

Length is measured from under the head.

Lightweight Ultra-Corrosion-Resistant Grade 2 Titanium—Often used in chemical-processing and water-treatment plants, these stand up to strong acids and other harsh chemicals.

Titanium Button Head Hex-Drive Screws

Made of grade 5 titanium, these screws are nearly as strong as alloy steel but only 40% of the weight. More corrosion resistant than stainless steel, these screws stand up to salt water, strong acids, and harsh chemicals. The button head looks similar to a pan head, but it's lower and more compact, taking up less space. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver.

Length is measured from under the head.
