WESTWARD H4

Westward is a brand of power tool components and accessories, with the H4 series representing a line of precision-machined parts used in industrial tooling and equipment maintenance. The H4 product family includes tapers, plugs, and bottom components, each designed to specific thread standards such as 3/8-24NF, 1/4-28NF, 5/16-24NF, 7/8-14NF, and 1-14NF. These parts are manufactured to fit Westward-brand tools, with compatibility across models like 1PZ33, 1PZ35, 1PZ36, 1PZ37, and 1PZ38. The components are typically used in applications requiring precise thread engagement and dimensional accuracy, such as in pneumatic or hydraulic tool assemblies, jigs, fixtures, or replacement parts for industrial machinery. The H4 taper components (e.g., SKU 45L537, 45U126, 45T623) are designed for securing tooling or workpieces, while the H4 plug components (e.g., SKU 45L540, 45T920, 45N156, 45L541) serve as sealing or alignment elements. The H4 bottom component (SKU 45L532) provides a base or stop function. All parts are identified by manufacturer part numbers (MPNs) such as 440-1232, 440-2374, 440-2232, 440-2142, 440-1142, 440-1176, 440-3232, and 440-2394, which facilitate cross-referencing and inventory management. 3G Electric stocks multiple SKUs of Westward H4 power tool parts, offering global logistics support for procurement specialists and maintenance managers. The parts are supplied as individual components, allowing engineers to replace worn or damaged elements without replacing entire assemblies. The thread specifications (NF, or National Fine) indicate compatibility with standard fine-thread fasteners, ensuring interchangeability in existing systems. The H4 series is suited for environments where repeatable precision and durability are required, such as in manufacturing plants, repair shops, and field service operations. 3G Electric's catalog provides detailed specifications for each SKU, including compatible tool models and thread dimensions, enabling buyers to verify fitment before ordering. The availability of multiple thread sizes and component types within the H4 line supports a range of maintenance and repair tasks, from simple plug replacements to complex taper adjustments. By sourcing from 3G Electric, industrial buyers can access these parts without minimum order constraints, with shipping options tailored to project timelines.

Frequently asked questions

Common questions about WESTWARD H4 from 3G Electric.

What thread standards are available for Westward H4 plugs and tapers?

Westward H4 plugs and tapers are available in several National Fine (NF) thread standards: 1/4-28NF, 5/16-24NF, 3/8-24NF, 7/8-14NF, and 1-14NF. These fine-pitch threads provide secure engagement in applications requiring vibration resistance or precise adjustment. Each part is labeled with its thread size and type, such as 'H4 Plug, 3/8-24NF' or 'H4 Taper, 1/4-28NF', allowing direct matching to existing tooling or equipment specifications.

Which Westward tool models are compatible with H4 components?

Westward H4 components are designed to fit specific Westward tool models. For example, H4 tapers (SKUs 45L537, 45U126, 45T623) and the H4 bottom (SKU 45L532) are compatible with model 1PZ38. H4 plugs (SKUs 45L540, 45L541) fit model 1PZ37, while other plugs (SKUs 45T920, 45N156) fit models 1PZ33, 1PZ35, 1PZ36, and 1PZ37. Always verify the model number listed in the product specifications before ordering.

What is the difference between a Westward H4 taper and an H4 plug?

A Westward H4 taper is a conical component used to secure tooling or workpieces by providing a wedging action, typically in a matching socket. An H4 plug is a cylindrical part with external threads, used to seal or close an opening, or to serve as a stop or alignment feature. Both are precision-machined to NF thread standards, but their functional roles differ: tapers for retention, plugs for sealing or positioning.

Are Westward H4 parts interchangeable with other brands?

Westward H4 parts are manufactured to fit Westward-brand tools and are not guaranteed to be interchangeable with other brands. The thread dimensions and taper angles are specific to Westward's design specifications. For replacement or repair, it is recommended to use Westward H4 components to ensure proper fit and performance. Cross-referencing with manufacturer part numbers (MPNs) can help identify correct replacements.

How can I identify the correct Westward H4 part for my application?

To identify the correct Westward H4 part, check the tool model number (e.g., 1PZ33, 1PZ35, 1PZ36, 1PZ37, 1PZ38) and the required thread size and type (e.g., 3/8-24NF). Each SKU in 3G Electric's catalog lists the compatible model and thread specification. Additionally, the manufacturer part number (MPN) such as 440-1232 or 440-2374 can be used for precise matching. If unsure, consult the tool's manual or contact 3G Electric's support with the tool model and thread details.
