Prepare the Nail Strip: Ensure nails are aligned, straight, and compatible with Bostitch SB-1664FN specifications before loading
Before loading nails into the Bostitch SB-1664FN, inspect the nail strip to ensure it meets the tool’s precise requirements. The SB-1664FN is designed to work with 16-gauge straight finish nails ranging from 1 to 2½ inches in length. Verify the nail strip’s gauge and length compatibility by checking the packaging or manufacturer specifications. Using incompatible nails can lead to jams, misfires, or damage to the tool, so this step is non-negotiable. Always prioritize nails from reputable brands known for consistent quality, as poorly manufactured nails may have irregular shapes or coatings that hinder proper feeding.
Alignment is critical for seamless operation. Hold the nail strip up to a straight edge or light source to confirm that the nails are perfectly straight and evenly spaced. Bent or misaligned nails can cause the strip to bind in the magazine, disrupting the loading process and potentially damaging internal components. If you notice any irregularities, discard the strip and select a new one. For bulk nail purchases, consider using a nail alignment tool or jig to pre-sort and straighten nails before loading, especially if storing nails in environments prone to humidity or rough handling.
Compatibility extends beyond size to include the nail strip’s collation method. The SB-1664FN is engineered to work with plastic-collated nail strips, which are lighter and less prone to corrosion than wire-collated alternatives. Plastic collation also reduces friction within the magazine, ensuring smoother feeding. Avoid using wire-collated nails, as they may not fit properly and can cause excessive wear on the tool’s internal mechanisms. If unsure, consult the tool’s manual or contact Bostitch customer support for clarification on compatible collation types.
A practical tip for ensuring nail strip readiness is to gently tap the strip on a flat surface to settle the nails into a uniform position. This simple action can help correct minor misalignments caused by packaging or handling. Additionally, store nail strips in a dry, climate-controlled environment to prevent warping or rust, which can compromise alignment and compatibility. By taking these preparatory steps, you’ll minimize the risk of loading issues and maximize the efficiency and longevity of your Bostitch SB-1664FN.

Open the Magazine: Release the latch and slide the magazine out to access the loading area
The Bostitch SB-1664FN's magazine is the gateway to efficient nail loading, but it’s not as simple as just sliding it open. A latch mechanism secures the magazine in place, ensuring stability during operation while also preventing accidental openings. To begin the loading process, locate the latch, typically positioned near the base of the magazine. Apply gentle pressure to release it, ensuring you don’t force it, as excessive force can damage the mechanism. Once released, the magazine should slide out smoothly, revealing the loading area. This design balances accessibility with safety, a hallmark of Bostitch’s engineering.
Analyzing the latch and slide mechanism reveals its dual purpose: it safeguards the operator from potential jams or misfires while maintaining the tool’s structural integrity. Unlike some nailers that rely on complex locking systems, the SB-1664FN prioritizes simplicity without compromising functionality. This approach reduces user error, especially for those new to pneumatic tools. However, it’s crucial to inspect the latch periodically for wear or debris buildup, as these factors can hinder smooth operation. A well-maintained latch ensures consistent performance, saving time and frustration in the long run.
For optimal results, follow these steps: first, ensure the nailer is disconnected from the air supply to prevent accidental firing. Next, position the tool on a stable surface to avoid tipping. With one hand, depress the latch firmly but gently, using your other hand to pull the magazine outward in a steady motion. If resistance is encountered, double-check for obstructions or misalignment. Once the magazine is fully extended, you’ll have clear access to the loading channel, ready to insert a new nail strip. This process should take no more than 10 seconds when done correctly.
Comparing the SB-1664FN’s magazine design to competitors highlights its user-centric approach. Some models require tools to open the magazine or have latches that are difficult to locate, adding unnecessary steps. Bostitch’s design, however, emphasizes ergonomics and efficiency, making it ideal for both professionals and DIY enthusiasts. For instance, the latch’s tactile feedback ensures users know when it’s fully released, reducing guesswork. This attention to detail sets it apart in a crowded market, where ease of use can significantly impact productivity.
Finally, a practical tip: if the magazine feels stiff or resists sliding, apply a small amount of silicone-based lubricant to the rails. Avoid oil-based products, as they can attract dust and debris, exacerbating the issue. Regular cleaning of the loading area is equally important, as debris can interfere with nail feeding. By incorporating these maintenance practices, you’ll ensure the SB-1664FN’s magazine operates smoothly, extending the tool’s lifespan and maintaining its reliability for years to come.

Insert Nail Strip: Place the nail strip into the magazine channel with heads facing outward
The Bostitch SB-1664FN nailer is designed for efficiency, but its performance hinges on proper nail strip insertion. Misalignment or incorrect orientation can lead to jams, misfires, or damage to the tool. The critical step here is placing the nail strip into the magazine channel with the heads facing outward. This ensures smooth feeding and consistent firing, maximizing the tool’s reliability on the job site.
Consider the anatomy of the nail strip and the magazine channel. The channel is engineered to guide the nails in a straight line, with the heads acting as a stabilizing force. If the heads face inward, they can catch on the channel’s edges or interfere with the pusher mechanism, causing jams. By positioning the heads outward, you create a flush alignment that allows the nails to glide effortlessly toward the firing chamber. This simple yet crucial detail is often overlooked, leading to frustration and downtime.
To execute this step effectively, start by inspecting the nail strip for defects or bent nails, which can disrupt loading. Hold the strip firmly at a slight angle, aligning the first nail with the channel’s entrance. Gently slide the strip into the channel, ensuring the heads are flush against the outer edge. Once fully inserted, release the magazine latch to secure the strip in place. A properly loaded strip should move freely when the pusher is engaged, indicating correct alignment.
Practical tips can further streamline this process. For instance, use Bostitch-branded nail strips, as they are specifically designed for compatibility with the SB-1664FN. Avoid overloading the magazine, as this can cause binding. If resistance is felt during insertion, stop and recheck the orientation—forcing the strip can damage the tool. Lastly, always wear safety gear, as mishandling nails or the nailer can result in injury.
In comparison to other nailers, the SB-1664FN’s loading mechanism is straightforward but demands precision. Unlike some models that auto-adjust for nail orientation, this tool relies on the user’s attention to detail. By mastering this step, you not only ensure optimal performance but also extend the tool’s lifespan. Proper nail strip insertion is a small action with a significant impact, transforming a potential headache into seamless operation.
