Onverliesbare schroeven

 (8 productgroepen)

Wat zijn onverliesbare schroeven?

Onverliesbare schroeven zijn bevestigingsmiddelen die zijn ontworpen om aan beschermingselementen of apparatuur te worden bevestigd. Conventionele schroeven worden meestal door een spelingsgat in één deel gevoerd en in een draadgat in een tweede deel vastgeschroefd, zodat het eerste deel aan het tweede deel vast komt te zitten. Als het bevestigingsmiddel echter van het draadgat van het tweede component wordt losgeschroefd, kan de conventionele schroef gemakkelijk van het eerste component worden gescheiden. Onverliesbare schroeven zijn ontworpen om te voorkomen dat dit gebeurt. De schroef kan vrij roteren in de eerste set, met enige axiale beweging, maar kan er niet van loskomen.
Een onverliesbare schroef is een gespecialiseerd bevestigingsmiddel dat past in een doelmontage of behuizing en heeft typisch een deel zonder schroefdraad onder de kop dat een verloopstuk heet. De schroef zit vast, wat betekent dat ze niet volledig uit het gat komt of er niet uitvalt als het item wordt losgemaakt. Onverliesbare schroeven bieden een permanente houvast en kunnen nog steeds uit de installatie worden verwijderd, maar alleen wanneer dit de bedoeling is.

Voordelen van onverliesbare schroeven

Onverliesbare schroeven bieden een aanzienlijke kostenbesparing door de montagetijd en het aantal nodige componenten te verminderen. Bovendien kunnen ze de esthetiek van een product verbeteren, omdat de schroeven gedurende het hele proces op hun plaats blijven. Bovendien wordt de betrouwbaarheid verbeterd door de veilige aard van de onverliesbare schroeven, wat resulteert in minder potentiële storingen of verloren onderdelen. Tot slot wordt het risico op letsel verminderd, omdat onverliesbare schroeven geen risico's met zich meebrengen die kunnen worden veroorzaakt door losse schroeven.

Hoe kan een onverliesbare schroef worden geplaatst?

Onverliesbare schroeven zijn eenvoudig te bevestigen en worden meestal gebruikt met een borgflens of een borgring. Om een onverliesbare schroef met een borgflens te bevestigen, moet de flens eerst op het paneel worden gedrukt. De onverliesbare schroef moet dan in de flens worden geschroefd tot de sectie met een kleinere diameter wordt bereikt.

Captive Screws - Pan Head

Op voorraad Klik hier om de actuele levertijd aan te vragen.

This range of Captive Screws have a pan head with two options: one with a Torx drive and one with a Philips drive. On the one hand, Screws with Torx drive provide a positive, quick engagement that transmits torque with less downward pressure. In contrast, screws Philips drive can withstand high torque, making them a good choice for applications requiring a tight fit and making the screw easy to remove, even if it has been driven in tightly. They both offer an excellent fastening appearance, ideal for finished product presentation.

These screws are an ideal fitting solution for panels with non-threaded holes. The M8 sizes have a reduced Torx, while the M3, M4, M5, and M6 sizes have a Philips drive. They are used to comply with the Machinery Detective 2006/42/EC - generally to ISO 14583. Captive Screws are commonly used with Threaded Captive Washers (sold separately).

Captive Screws - Button Head

Op voorraad Klik hier om de actuele levertijd aan te vragen.

Captive Screws are fasteners designed to remain attached to the component they are securing, even when fully loosened, providing convenience, security and ease of use in a variety of applications. They are a popular choice for applications where screws need to be removed frequently or where safety is a concern, as these screws will stay firmly in place and will not loosen from the assembly.

This range of Captive Screws has a button head and a Torx drive. Torx drives provide a positive-engaging, fast-locating technique for transmitting drive torque with less necessary downward pressure. They are an excellent fitting option for panels with non-threaded holes when used in conjunction with our threaded captive washers. They are used to comply with Machinery Detective 2006/42/EC - typically to ISO 14583, which requires fasteners to stay attached to fixed guards or applications when they are removed.

The screws are made from Stainless Steel, which is corrosion resistant and slightly magnetic, and you can find a group of screws with a blackened finish and others without.These screws are commonly used in electronics, industrial machinery, cabinets, panels and medical devices. Please keep in mind that because these screws have a smaller shank diameter, they should not be tightened to the suggested torque for an identical screw with the same thread size.
