Hex washer shoulder bolt non thread phillips customized

Hex washer shoulder bolt is the bolt with hex washer head and non threaded. The bolt with an unthreaded shoulder that is larger in diameter than the tail. Ever Hardware provide custom made hex washer shoulder bolt and customizable packaging.

Hex washer head combines the advantages of the phex head but has a washer built on to the head to increase head diameter and prevent over driving in soft parts while providing a maximum bearing surface.

Phillips is the most commonly screw drive. The Phillips screw drive was created by John P. Thompson, who after failing to interest manufacturers, sold his design to businessman Henry F. Phillips. Phillips is credited with forming a company (Phillips Screw Company), improving the design, and promoting the adoption of his product. The original patent expired in 1966, but the Phillips Screw Company continued to develop improved designs.
Phillips drive bits are often designated by the letters “PH”, plus a size code 0000, 000, 00, 0, 1, 2, 3, or 4 (by order of increasing size); the numerical bit size codes do not necessarily correspond to nominal screw size numbers.

Yellow zinc coating prevent oxidation of the hex washer shoulder bolt by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not cause a breakdown of the substrate’s surface integrity as it is formed. Indeed, the zinc oxide, if undisturbed, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers. The majority of hardware parts are zinc-plated, rather than cadmium-plated.

Ever Hardware is a young company, but we are not a young team.
