Delta Single Handle Shower Set Screw Will Not Come Out

Delta Single Handle Shower Set Screw: Why Won't It Budge? A Troubleshooting Guide

Dealing with a stubborn Delta single handle shower set screw can be incredibly frustrating. This guide provides a step-by-step approach to diagnosing and resolving this common plumbing problem, helping you avoid costly plumber calls. We'll cover why the screw might be stuck, and various techniques to loosen it, from simple methods to more advanced solutions.

Why Your Delta Shower Set Screw Is Stuck:

Several factors can contribute to a jammed set screw. Understanding these potential causes is the first step towards fixing the problem. Common culprits include:

• Corrosion: Over time, moisture and mineral deposits can cause the screw and its threads to corrode, leading to seizing. This is particularly prevalent in areas with hard water.
• Over-tightening: Previous attempts to tighten the screw may have stripped the threads or over-tightened it beyond its breaking point.
• Paint or sealant: Paint, caulk, or sealant accidentally applied during installation or renovation can lock the screw in place.
• Damaged screw head: A stripped or damaged screw head makes it nearly impossible to grip with a standard screwdriver.
• Worn-out threads: Years of use and temperature fluctuations can damage the threads, preventing smooth turning.

Troubleshooting Steps: Getting That Stubborn Screw Loose

Before you resort to drastic measures, try these techniques:

1. Preparation is Key: The Right Tools and Approach

• Penetrating oil: This is your best friend! Apply a generous amount of penetrating oil (like WD-40 or PB Blaster) to the screw head and surrounding area. Let it soak for at least 30 minutes, or even overnight for stubborn cases. The oil will seep into the threads, breaking down corrosion and lubricating the mechanism.
• Appropriate screwdriver: Use a screwdriver that precisely matches the screw head's size and type. A worn-out or improperly sized screwdriver will likely strip the head further. Consider using a magnetic tip screwdriver for better grip.
• Proper technique: Apply steady, even pressure when turning the screw. Avoid excessive force, as this can damage the handle or strip the screw. Try turning the screw both clockwise and counter-clockwise gently to break any binding.

2. Employing Gentle Persuasion

• Heat: Apply gentle heat to the area around the screw using a hairdryer or heat gun. Heat expands metal, potentially breaking the bond of corrosion. Be cautious not to overheat the plastic parts of the handle.
• Impact driver: If a regular screwdriver isn't working, an impact driver can provide the extra force needed to loosen the screw. Use a low setting to avoid damaging the handle.

3. Advanced Techniques (When All Else Fails)

• Screw extraction tools: If the screw head is severely damaged, you may need to use screw extraction tools to remove the remaining screw. These tools are readily available at hardware stores and can work wonders.
• Dremel tool: As a last resort, carefully use a Dremel tool with a small cutting bit to create a slot in the screw head if it's stripped. This allows for the use of a flathead screwdriver. Proceed with extreme caution to avoid damaging surrounding components.
• Professional help: If all else fails, it's best to call a qualified plumber. They possess the expertise and tools to handle complex situations safely and efficiently.

Preventing Future Problems:

• Regular maintenance: Periodically apply lubricating oil to the shower handle mechanism to prevent corrosion and ensure smooth operation.
• Careful tightening: Avoid over-tightening the set screw during future maintenance or repairs.
• Proper cleaning: Regularly clean your shower handle to remove mineral deposits and prevent buildup.

By following these steps, you should be able to resolve your Delta single handle shower set screw issue. Remember, patience and the right tools are key to success. If you're hesitant to tackle the job yourself, remember that calling a professional is always an option.
