Ripeng Long Outlet Screws Set (1.5″ Reach)
The Ripeng set includes 30 extra-long machine screws with a cross recess pan head, each at 1.5 inches. Best for mounting backsplash extenders or deep outlet boxes where standard screws won’t reach. They’re designed to resist rust and corrosion, thanks to stainless steel construction. Suitable for fixed sockets, outlets, switches, and dimmers. A potential limitation is the relatively narrow length range if you need longer than 1.5 inches.
Who it’s best for: DIYers tackling deep boxes or backsplashes who need a compact, single-purpose long-screw solution. Why selected: combination of length, corrosion resistance, and versatile head design makes mounting straightforward in many common installations.

This comprehensive assortment includes six lengths, with extended 1-1/4 inch options for deep backsplashes or granite backsplashes and standard 6-32 threads to fit typical light switches and outlet covers. The carbon steel body with a white baked-on coating resists rust and chipping. Best for professional finishes and replacement during upgrades; avoid if you need non-white finishes. Caution: ensure you match the wall plate color for the best aesthetic result.

Outer diameter 10 mm, inner diameter 4 mm, designed to accommodate deep outlets and provide precise depth control. Best for complex wall setups or projects needing multiple spacer sizes. Choose this if you want a large, flexible toolkit for multiple rooms; caution: the kit’s size may be more than necessary for small jobs.

Flat head, cross recess machine screws in a 6-32 size, at 1-1/2 inches. Built for fix-it scenarios where outlets sit deeper than standard boxes.

Buying Guide
Key considerations when choosing long outlet screws:
- Length and depth: Match screw length to your box depth and backsplash thickness. Longer screws reach deeper mounting points; avoid overly long screws that protrude beyond the mounting surface.
- Material and corrosion resistance: Stainless steel offers superior rust resistance for humid bathrooms or kitchens; carbon steel with a protective coating is a cost-effective alternative.
- Head type: Flat heads sit flush for a neat finish; pan or round heads may provide easier driving in tight spaces.
- Thread size: Most residential boxes use 6-32 or 8-32 threads. Ensure compatibility with your outlets, switches, and wall plates.
- Finish: White-painted heads blend with white outlets; consider color-matched options for a cleaner look.
- Quantity and versatility: Kits with spacers and multiple lengths can simplify upgrades across multiple rooms, but may be more than you need for a single project.
Frequently Asked Questions
- What length should I choose for a deep electrical box?
Choose screws around 1-1/2″ to 1-3/4″ if you’re dealing with deep outlets or thick backsplashes, ensuring the screw reaches into the box securely. - Are stainless steel screws better for moisture-prone areas?
Yes. Stainless steel resists rust and corrosion, making them suitable for bathrooms and kitchens. - What thread size is most common for US outlets?
Most are 6-32 or 8-32 threads; confirm the thread size with your existing screws or wall plates. - Should I buy a mixed-length kit or single-length screws?
A mixed-length kit offers flexibility for various projects, while single-length packs can be sufficient for a single upgrade. - Is a white-painted finish necessary?
A white finish helps match white outlets and wall plates; non-white finishes may be preferred for color-matched installations. - Can I reuse screws from old installations?
Only if they are the correct length, thread size, and condition. Worn or bent screws should be replaced to ensure a secure mount.
