SPIROL designs and manufactures specific types of Solid Pins to meet the performance and assembly requirements of common niche applications. These Solid Pins are variations of our standard product either manufactured from specific material, have a specific finish or undergo specific processing to meet performance, corrosion, compatibility and assembly requirements for the specific application. These pre-designed application-specific series of Solid Pins help companies shorten the design cycle to confidently launch their product quickly to the market with a pinning solution that has been tested and proven within their assembly.

Latch Pins for Plastics
SPIROL's Series LP500 Latch Pins for Plastics are designed with a barb located under the head with a barb length equal to the width of the outermost section of the assembly. The remaining length of the LP500 Latch Pin is smooth without any other retention features. This allows the LP500 Latch Pin for Plastic to easily align and freely install through all of the holes with a plastic assembly until the barb makes contact with the final hole to securely lock the pin in place. Once fully installed, the handle will pivot freely around the non-barbed end of the stationary pin. The head prevents the LP500 Latch Pin from being over-installed, and enables the pin to be mechanically oriented for automatic installation. Manufactured from lightweight, lead free aluminum, SPIROL's LP500 Latch Pins for Plastics are available in three standard diameters: 3mm, 4mm and 5mm.
Series RH600 Twist-Lok™ Pins replace costly screw machined pins and eliminate problematic installation of screws and rivets. The helical knurl minimizes stress during installation by rotating as it engages the hinge. Corrosion-resistant material and a rounded burr-free head improve installed appearance. Axial and radial forces induced in the hinge eliminate the tendency for the pin to creep and maintain hinge tension.

Application Success Stories
Hinge Pin in Automotive Interior Door Handle Latch Mechanism
An automotive door handle manufacturer approached SPIROL to recommend a hinge pin that would eliminate the BSR (buzz, squeak & rattle) caused by a semi-tubular rivet they were using in their assembly.
- SPIROL’s LP500 Latch Pin for Plastics was specifically developed for the automotive handle and latch market.
- The barbed section under the head of the LP500 Latch Pin for Plastics locks the pin into the plastic host assuring the handle pivots properly while the pin remains stationary. This also completely eliminates the concern for BSR.
- Since the pin is pressed securely into place upon insertion, all secondary operations such as riveting and peening are eliminated.
- Replacing the current Semi-Tubular Rivet with SPIROL’s LP500 Latch Pin for Plastics simplified the assembly process, improved production efficiencies, eliminated lubricants, and improved the overall product quality of the door handle.
