Dorman 700-089 Splash Shield Screw Bolt with Captive Washer

Best for: Auto enthusiasts and maintenance technicians needing a durable M10-1.5 x 26.5 mm screw with a captive washer. This part is manufactured to precise thread tolerance standards, and it has undergone salt spray testing to verify corrosion resistance. The versatile design supports a range of applications beyond automotive use, including home projects where a captive washer helps prevent loss during disassembly.
Key considerations: Choose this if you require proven corrosion resistance and a standard metric thread. The data supports broad compatibility, but check your vehicle’s specific fastener size before ordering.
AR-PRO 79104800 Pool Light Gasket Screws with Washers

Best for: Pool and spa technicians needing a precise 1-1/4″ pilot screw with captive gum washer for Pentair pool light niches. These screws are designed to fit Pentair IntelliBrite, Amerlite, and SAM Amerlite lighting systems and provide secure grounding paths when installed. They are ideal for maintenance crews replacing underwater lighting components.
Caution: Confirm exact length and thread match for your pool light housing to avoid improper seating. The captive gum washer helps prevent losses if disassembled underwater, but improper fit can still cause leaks if the face ring isn’t properly seated.
APDTY 173263 Splash Shield Screw Bolt with Captive Washer

Best for: Vehicle owners needing a ready-to-fit M10-1.5 x 26.5MM captive washer screw. The kit notes compatibility with several part numbers (11517817, 11518341, 24503929), aiding precise replacement alignment. This is a practical choice for universal splash shield replacements where exact match is listed.
Limitation: Always verify compatibility with your make/model against the provided compatibility chart to ensure exact fitment before purchasing.
(1000) Phillips Pan Head SEMs 10-32 x 3/8 Machine Screw Captive Washer EXT

Best for: General purpose machine screws in 10-32 size with captive washers, suitable for electronics, enclosures, and mounting brackets where a clean, integrated washer is beneficial. The capsuled washer helps prevent loss during disassembly.
Limitation: Not explicitly automotive-specific; verify thread size and head type against your project requirements before buying.
AC Infinity 10/32 Rack Screws and Nylon Washers

Best for: Equipment racks and enclosures needing self-guiding pilot point screws with nylon washers. The carbon steel screws feature corrosion and rust resistance due to black zinc chromate plating, making them suitable for server rooms and network cabinets.
Better for: Rail-mounted or rack-mount equipment where a flush finish is important. The included nylon washers help cushion and reduce vibration, though they may not be ideal in extremely high-temperature environments.
Pentair 619355 Stainless Steel Pilot Screw

Best for: Pool lighting replacements requiring a captive gum washer and compatibility with Pentair IntelliBrite 5g, Amerlite, and AmerQuartz systems. This pilot screw is sized to fit specific Pentair light assemblies and ensures a reliable ground path when installed correctly.
Limitation: Only suitable for certain Pentair lighting configurations; verify model compatibility before purchase.
Hillman 3140 8 x 1-Inch Oval Phillips Trim Screw with Washer

Best for: Trim and finishing work where an oval head provides a clean look and a washer helps distribute load. The black phosphate coating adds corrosion resistance and a tidy appearance for automotive interiors and furniture projects.
Tip: Suitable for projects needing a non-standard head shape; use where a flush, decorative finish is needed. Avoid using in high-stress structural applications where purpose-built fasteners are required.
Buying Guide
What is a captive washer and why does it matter?
A captive washer stays attached to the screw, reducing the risk of losing the washer during disassembly or underwater work. This feature is especially useful for automotive underbody work, pool lights, and equipment enclosures where small parts can be difficult to recover.
Material and corrosion resistance
Most screws with captive washers in this guide use stainless steel, carbon steel with protective plating, or zinc-coated finishes. Stainless steel is ideal for pool and outdoor use, while plated carbon steel offers cost-effective corrosion resistance for indoor projects.
Thread size and compatibility
Common sizes in this list include M10-1.5 and #10-32. Always verify thread pitch and length against your replacement part or manufacturer specification to ensure a proper fit.
Best practices for selecting
- Automotive needs: prioritize metric sizes and splash-shield compatibility.
- Pool/spa installations: look for stainless steel screws with captive washers and proper niche compatibility.
- Enclosures and electronics: consider #8-32 or #10-32 size with nylon or gum washers to manage vibration.
Frequently asked questions
- What is the advantage of a captive washer?
It prevents losing the washer and speeds up installation or maintenance by keeping all parts together.
- Are these screws suitable for outdoor use?
Many are corrosion-resistant (stainless steel or plated carbon steel) and designed for outdoor or wet environments, but always check exact material specs.
- How do I choose the right size?
Match the screw diameter and thread pitch to the original fastener or the manufacturer’s replacement guide.
- Can captive washers be replaced separately?
In most cases, the washer is integrated with the screw, so you replace the entire fastener if needed.
- Do these screws require special tools?
Most require standard screwdrivers or hex drivers corresponding to the head type; confirm drive type in product specs.
