Are you looking to buy bolts and metal screws?
At ManoMano, you can purchase HETTICH, SCELL-IT, VISSAL metal screws at a low price from our extensive catalogue. The metal screw, often incorrectly referred to as a bolt or bolt body, enables the solid and lasting fixation of metal parts such as hinges and frameworks.
ManoMano offers you a wide selection of metal screws in steel, brass, stainless steel A2... with all types of heads (cylindrical, TRL, countersunk, TBHC, TRCC, TCF, etc.). The most common drives are square recess, hex recess, slotted, and hex head.
For anchoring them, it's necessary to pre-drill the item or items to be fixed with a diameter equal to that of the screw minus the thread depth for a stronger fixation.
Then, the choice of material will depend on the environment and the forces exerted on your fixture (stainless steel for outdoor, steel for high hardness, and brass for more flexibility), the choice of the drive type will more depend on the space, accessibility, and the required torque for your fixture.
Metal screws are generally used with a nut to complete the fixation system. Some nuts may offer anti-vibration features or may be blind (open on one side only) to protect and secure the end of the screw. Being very rigorous in your choice of nuts is necessary, as the pitch and the depth of the thread are very important data, as well as the material and shape of it. Indeed, some metals are more flexible and less brittle than steel but offer lower hardness.
Also, the screw + bolt system is very often accompanied by washers. These seemingly basic little tools are highly valued for constructing durable fixations. Placed under the head and on the nut, they distribute the compression force over a larger surface and thus preserve the support. Depending on their composition, washers are also used to limit vibrations or friction that could weaken the fixture.
