Hillman 59381 Connecting Bolt M6 x 42mm Heavy Duty Hex Bolt 20 Pack

Description

Product Overview

The Hillman 59381 Connecting Bolt is engineered for demanding applications where strength, reliability, and precision are paramount. Constructed from high‑grade steel and conforming to the ISO 8.8 standard, each bolt delivers a tensile strength that exceeds typical commercial fasteners. The M6 thread diameter combined with a 42mm overall length provides ample engagement depth for a wide range of wood, metal, and composite substrates. The hexagonal head, designed for standard 6mm wrenches, ensures a secure torque transfer while minimizing the risk of cam‑out during installation. Finished with a plain, corrosion‑resistant coating, these bolts maintain their structural integrity even in humid or mildly corrosive environments, making them suitable for both indoor and outdoor projects. The 20‑piece packaging offers a cost‑effective solution for bulk purchases, reducing the need for frequent reordering and ensuring that you always have the right fastener on hand.

Usage

These heavy‑duty connecting bolts excel in a variety of settings, from professional construction sites to hobbyist workshops. In residential construction, they are ideal for securing wooden joists, framing walls, and attaching hardware to structural members. Their robust design also makes them a preferred choice for industrial equipment assembly, where vibration resistance and long‑term durability are critical. For commercial applications, such as retail fixtures, display units, and modular shelving, the bolts provide a clean, professional finish while ensuring that load‑bearing components remain firmly attached. Additionally, the metric thread profile (M6) aligns with international standards, simplifying cross‑border procurement and reducing the need for multiple inventory SKUs. Whether you are building a deck, assembling a metal frame, or repairing a wooden gate, the Hillman 59381 offers the confidence of a secure, lasting connection.

FAQ

What is the recommended torque setting for these bolts?

For an 8.8 grade M6 bolt, a typical torque range is 7–9 Nm (Newton‑meters). Adjust the torque based on the specific material and application to avoid over‑tightening.

Can these bolts be used with stainless steel components?

Yes, the hex head and thread profile are compatible with stainless steel parts. However, consider using a matching stainless steel washer to prevent galvanic corrosion.

Are the bolts suitable for outdoor installations?

The plain coating provides basic corrosion resistance, making the bolts suitable for most outdoor environments. For highly corrosive settings, a supplemental protective coating or stainless steel variant is recommended.
