About Hex Head Screws and Bolts
More
T-Bolts
Also known as tank-strap bolts, these T-bolts are commonly used with a band clamp or a strap to hold fuel tanks and other objects in place. The large T-shaped head provides a secure grip for steady tightening. Length is measured from the top of the head.
Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch.
Steel T-bolts without a finish are ready to be painted or finished.
Black-oxide steel T-bolts are mildly corrosion resistant in dry environments.
Zinc-plated steel T-bolts resist corrosion in wet environments.

T-Bolts with Collar
Also known as clamping pins, these bolts have a collar that slides along the shaft and can be welded in place to hold work and prevent over torquing. The large T-shaped head provides a secure grip for steady tightening. The black-oxide finish provides corrosion resistance in dry environments. Length is measured from the top of the head.

T-Handle Retractable Spring Plungers
 |  With Thread Locker |
 Without Thread Locker |
Lock the nose into the retracted position by pulling the handle and rotating it 90°. These spring plungers have a long nose that provides a large bearing surface to handle side loads.
Steel is strong and wear resistant. Zinc-plated steel bodies resist corrosion in wet environments.
Stainless steel is chemical resistant and may be mildly magnetic.
Spring plungers without thread locker are for use in soft material such as aluminum, in extreme temperatures, and on parts requiring frequent assembly and removal.
Spring plungers with thread locker have a nylon locking patch that adds friction to resist loosening.
Extended nose force is the force required to begin to depress the nose. Compressed nose force is the force required to depress the nose flush with the body. When using a plunger as a detent or stop, a lighter nose force with a shallower hole releases more easily, while a heavier force with a deeper hole holds more securely.

Threaded-Hole Knobs
Install these knobs on a threaded stud. They provide a secure grip to position, tighten, and hold fixtures, equipment, and machinery.
Plastic knobs are a lightweight alternative to metal. They resist oil, grease, and solvents. Nylon has good wear resistance.
