Engineered Specials
Z-Form®
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
PlasTORX®
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
Cold Formed Specials
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
Pins
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
REVEL™
REVEL™ STUD
REVEL™ is a revolutionary sealing stud designed for use with
plain or coated soft metal (HRB 80 or less). Its unique dual-
sealing ring design provides a robust sealing solution without
the need for secondary sealing washers or chemical sealants.
An optional grounding ring that penetrates coatings to provide a
secure ground is also available.
FEATURES
► Dual-sealing rings designed for painted or unpainted surfaces, mild steel, or aluminum
► Optional grounding ring that penetrates coatings.
► Available in two standard flange/head diameters based on ISO 15071:2011 and DIN 1665. Other diameters available upon request.
BENEFITS
► Seals against fluids without the need for expensive chemical sealants or sealing washers resulting in a lower overall cost
► Sealing features are cold-formed in a die for consistent performance.
► Fast and easy installation— no significant installation changes required.
► Less damage to the clamped component compared to a standard flange bolt.
► The optional grounding ring is designed to minimize debris generation and generated debris is trapped by the sealing rings which results in minimal loose debris at installation.
Techniclean™
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
