uxcell 20-piece T-Slot Bolts M8x20mm Stainless Steel for 4545 Aluminum

Description

Product Overview

The uxcell 20‑piece T‑Slot bolt kit is a precision‑engineered fastening solution designed specifically for the 4545 series aluminum extrusion profile. Each bolt measures M8×20 mm and features a robust hammer‑head design that slides effortlessly into the T‑shaped slot, providing a secure, threaded connection that resists loosening under vibration and load. Constructed from high‑grade stainless steel, the bolts deliver exceptional corrosion resistance, ensuring long‑term performance even in harsh environments such as outdoor solar installations, industrial machinery, and marine applications. The package includes twenty individual bolts, each polished to a smooth finish that reduces friction during installation and minimizes wear on the extrusion profile.

Beyond the core specifications, the kit offers practical benefits that streamline the assembly process. The bolts are pre‑treated to eliminate surface contaminants, allowing for immediate use without additional cleaning or coating steps. Their standardized dimensions align perfectly with the 1.25 mm pitch of the 4545 extrusion, guaranteeing a tight fit that eliminates play and improves overall structural rigidity. The compact packaging dimensions of 5.51 × 3.94 × 0.59 inches make storage and transport straightforward, while the lightweight 9.28‑ounce total weight ensures easy handling on the job site.

Usage

These T‑Slot bolts excel in a wide range of applications where reliable fastening is critical. In modular framing systems, they secure aluminum rails to create sturdy workstations, workbenches, and equipment racks. The hammer‑head design enables quick insertion and removal, making reconfiguration of modular setups fast and tool‑free when a simple wrench is used for tightening. For solar panel mounting, the bolts provide a corrosion‑resistant anchor point that can withstand exposure to UV radiation, temperature fluctuations, and moisture, ensuring the longevity of the solar array.

In addition to industrial uses, the bolts are well‑suited for hobbyist projects such as custom furniture, speaker enclosures, and DIY robotics. Their precise threading allows for consistent torque application, which is essential when building load‑bearing structures or moving parts that require repeatable positioning. The bolts also integrate seamlessly with accessories like T‑slot brackets, clamps, and sliding panels, expanding the versatility of the 4545 extrusion system across creative and functional designs.

FAQ

What size T‑Slot bolts do I need for a 4545 aluminum extrusion?

The 4545 series uses a 1.25 mm pitch T‑slot, and the standard bolt size is M8×20 mm. Our uxcell kit includes exactly this size, ensuring a direct match without the need for adapters or additional hardware.

Can these bolts be used in outdoor solar panel installations?

Yes. The bolts are made from 304 stainless steel, which provides excellent resistance to rust, UV exposure, and temperature extremes. This makes them ideal for mounting solar panels, where long‑term durability is essential.

How do I install the hammer‑head T‑Slot bolts correctly?

First, align the bolt’s T‑shaped head with the corresponding slot in the aluminum extrusion. Press the bolt into the slot until it seats fully, then use a wrench to turn the threaded portion clockwise until snug. The design allows the bolt to self‑position, reducing the need for precise alignment tools.

What should I do if the bolt does not fit my extrusion profile?

Before purchasing, verify the profile’s dimensions and slot width. If the bolt appears too large or small, compare the measurements with the specifications listed in the product details. Our support team can help confirm compatibility or recommend an alternative size from our SKU range.

Is there a warranty or guarantee for these bolts?

uxcell offers a standard one‑year warranty covering material defects and manufacturing errors. If a bolt fails due to these issues, contact our customer service for a replacement. This warranty does not cover damage caused by improper installation or misuse.
