ZERO CLEARANCE BOLT AND SLEEVE ASSEMBLY

Typical bolted joints require clearance to accommodate machining tolerances and rely solely on clamp load to prevent joint slip. In joints subjected to high shear loads, traditional bolted joint assemblies may not be capable of keeping the clamped components from moving laterally in relation to each other. Dowel pins and locating sleeves are traditionally used to resist these shear loads.

The Z-Form® Assembly consists of a shoulder bolt with a pre-assembled deformable sleeve which, when installed completely eliminates clearance between the bolt and the through hole in the clamped component. This increases resistance to slippage, retains clamp load and extends gasket / seal life.

In one customer validation test involving a ring gear application, Z-Form® Bolt & Sleeve Assembly outperformed the existing fastener by achieving 18X the number of reversing cycles. As a result, fewer or smaller fasteners may be used while still retaining a longer lived and completely serviceable joint.

FEATURES

► Sleeve expanding shoulder
► Retained deformable sleeve
► Zero clearance joint interface

BENEFITS

► Extremely high level of torque capacity for drive line joints
► Prevents lateral slippage in joints subjected to high shear loads
► Allows for the use of fewer or smaller fasteners in many applications

FASTENER FOR INJECTION MOLDING

Special head designed specifically for high pull out and high torsional resistance in injection molded assemblies.

FEATURES

► Molded directly into application which increases assembly efficiency
► Provides maximum resistance to rotation and pull-out
► Allows multiple fasteners to be installed at one time

BENEFITS

► Reduces assembly time
► Reduces part number complexity
► Reduces overall costs

CUSTOM FASTENER DESIGNS

In addition to the “typical” fasteners that Acument Global Technologies manufacturers, there are other custom designs available as well. Many custom shapes and sizes can be manufactured to meet your needs. Let our Applications Engineers’ work with your team to develop the best solution for each application.

FEATURES

► Large head-to-shank ratios possible
► Uninterrupted grainflow
► Parts can be formed to net or near-net shape, which requires fewer secondary operations to achieve final shape

BENEFITS

► Improved strength and reliability through work hardening and uninterrupted grain flow
► Improved surface finish over screw-machined components
► Increased strength and lowered cost over screw-machined components

UNTHREADED PINS

Unthreaded pins can be used as locating fixtures, to rivet joints together, or to allow for rotating movement.

FEATURES

► Many custom diameters possible on single part
► Can use STRUX® family of parts to clinch pin to correct location
► Can hold tight diameter tolerances

BENEFITS

► Lower cost over screw-machined parts
► Exact design to fit needs of application

FASTENERS FOR TECHNICAL CLEANLINESS

As pneumatic, hydraulic and powertrain systems become more complex, they also become more susceptible to failures resulting from particle contamination. These failures can lead to excessive repair or replacement costs, which are driving manufacturing companies to seek out solutions to help prevent harmful particles from entering the system. To support these efforts, Acument Global Technologies developed and defined our own unique standard and classes of clean fasteners under the brand name TECHNICLEAN™. Conventional fasteners are bulk processed through equipment shared with other products, meaning the job is only as clean as the dirtiest part. Furthermore, many fasteners have specified finishes that aren’t conducive to meeting technical cleanliness requirements. TECHNICLEAN™ fasteners are manufactured with Acument Global Technologies industry leading processes and fastener finishes designed to help provide and ensure cleanliness levels superior to that of conventional fasteners.

FEATURES

► Innovative Acument TECHNICLEAN™ process designed to meet your cleanliness needs
► Standard Acument TECHNICLEAN™ 600 and TECHNICLEAN™ 900 or custom defined particle cleanliness service levels
► Clean finish options include phosphate and zinc electroplate
► Custom finish options can be evaluated upon request
► Routine cleanliness inspections based on ISO 16232

BENEFITS

► Helps minimize the risk of damage caused by particle contamination
► Provides for a consistent and defined level of product cleanliness quality with or without finish options
► Meets defined corrosion resistance and coefficient of friction requirements
► Helps ensure a consistent lowest possible level of harmful particles
