Huck ® Magna-Lok ® structural blind fasteners are mechanical fasteners designed to join two or more materials together in situations where access is limited to only one side of the joint .
What is the difference between a Rivet and a Huck ® structural blind rivet ?
A Huck ® structural blind rivet retains the pin in the rivet body ( sleeve ) post-installation for extra tensile and shear strength . This 360 ° internal locking technology enables the pin to be mechanically locked to the sleeve as it expands during installation , giving excellent joint tightness and highquality resistance to liquid penetration . The Huck ® 316 ( A4 ) stainless steel Magna- Lok ® is available in 6.4mm ( 1 / 4 ’’) diameter , with a wide grip range to accommodate variations in joint thickness ( 2.03mm -15.88mm).
316 Marine Grade ( A4 ) stainless Steel fasteners are specialised types of fasteners made from stainless steel alloy 316 , which is also known as A4 stainless steel . These fasteners are designed to provide excellent corrosion resistance , making them particularly well-suited for use in corrosive environments . Here ’ s more information about them .
Key advantages of 316 marine grade , non-magnetic Huck ® fasteners :
Non-Magnetic Properties : Non-magnetic fasteners are essential in environments where magnetic fields can disrupt sensitive electronic components or equipment . Industries such as medical imaging , telecommunications , and aerospace benefit from non-magnetic fasteners to maintain equipment performance . MRI scanners operate using powerful magnetic fields , and any magnetic interference can disrupt the accuracy and quality of the images . 316 stainless steel in non-magnetic variants , is chosen to prevent unwanted interactions with the magnetic field ,
Insert the fastener into the hole and slip the installation tool over the pintail .
Press the trigger to initiate pulling action . As the tool pulls on the pintail , the pin ( mandrel ) expands the sleeve and begins drawing the work pieces together .
ensuring that the material does not affect the scanner ’ s performance
Strength and Durability : Huck ® fasteners provide strong and reliable joints , often with load-carrying capabilities comparable to or even exceeding traditional fasteners .
Secure 316 stainless , Fast Installation
steel offers high tensile strength and durability , allowing fasteners to
1 . Flush pin break eliminates grinding and filling , leaving an even surface withstand significant loads and stresses .
2 . Unique solid-circle lock ensures maximum strength and resistance to vibration . The
Ease of Installation : Huck ® Magna-Lok ® structural blind fasteners are relatively easy to install , requiring minimal access to only one side of the joint .
potential for pin push-out is virtually eliminated
3 . Excellent gap pull-out and high retained clamp
Vibration Resistance : Huck ® fasteners offer excellent resistance to vibration , making them suitable for applications where the joint might experience movement or mechanical stress .
Corrosion Resistance : The primary advantage of using 316 stainless steel fasteners is their exceptional resistance to corrosion , making them ideal for applications exposed to moisture , saltwater , and other corrosive elements , such as marine environments .
Aesthetic Appeal : The smooth and polished appearance of stainless steel 316 gives a visually appealing finish to the fasteners , making them suitable for applications where aesthetics matter .
Continued pulling on the pintail draws the hollow pin head inside sleeve . The pin extrudes itself inside the sleeve and the work pieces completely expand the sleeve to match the hole of the work pieces .
4 . The sleeve expands during installation to fill the hole and create a moisture-resistant joint
A solid circle lock between the pin and sleeve is formed just prior to the pin breaking flush with the sleeve head , completing the installation .
Wide Range of Applications : 316 stainless steel fasteners find use in various industries , including marine , construction , outdoor structures , architectural projects , and more .
Low Maintenance : Thanks to their corrosion resistance , Huck ® fasteners generally require minimal maintenance over their lifespan .
Versatility : They can be used to join different materials , including metals and composites , expanding their applicability across industries .
Replaces Welding : In some cases , 316 Magna-Lok ’ s can replace the need for welding . 316 stainless steel is susceptible to weld decay ; the welded area can be more vulnerable to corrosion , weakening the bond of the weld . Weld decay primarily affects the microstructure of the material around the weld joint . When 316 stainless steel is heated to certain temperatures ( typically in the range of 800 to 1600 ° F or 425 to 870 ° C ) during welding , carbon in the steel combines with chromium to form chromium carbides . This process depletes the chromium content in the immediate vicinity of the weld joint , leading to a reduced ability to form a protective chromium oxide layer that provides the stainless steel ’ s corrosion resistance .
