Hex Cap Screws 18-8 Stainless Steel 1/4-20" Hellog 

GZ Industrial Supplies is a distributor and supplier of Hellog tools in Nigeria. This Hex Cap Screws 18-8 Stainless Steel 1/4-20" Hellog are bolts with a shoulder in lengths longer then 1-1/4". They have a hexagonal head, designed to be driven by a wrench. Commonly referred to as bolts or screws. These bolts are unique because of their threading. Hex cap screws are fully threaded in shorter lengths (usually around up to 1-1/4 inch, depending upon the bolt diameter), and partially threaded with a shoulder beneath the fastener hex head in longer lengths.

Our Hex Cap Screws 18-8 Stainless Steel 1/4-20" Hellog  are commonly used with nuts to secure an object in between the head of the bolt and the nut.

Though hex bolts go by many names the characteristic that they all share is a hexagonal head, designed to be driven by a wrench. They all are commonly referred to as both bolts and screws. They are unique because of the threading. These bolts are partially threaded with a shoulder beneath the head. Tap Bolts are fully threaded up to the hexagonal head. The unique characteristic of a hex bolt is the design of the head, from which they get their name. The "flange" of the bolt is a built in (integral) washer. In Imperial sizes, this washer is serrated to act as a lock washer. When a hex cap screw is fully threaded it can also be referred to as a tap bolt.
