HVAC/Metal Roofing Fastener Refresh
Offer a service replacing corroded 5/16 hex-head screws on metal roofs and HVAC curb/flashing panels. Use impact-rated deep sockets to protect painted heads, upsell to coated/self-sealing screws, and bill per square or per fastener.
Custom Magnetic Nut Drivers
Convert deep sockets into magnetized 5/16 nut drivers with color-coded bands, 3/8-to-1/4 adapters, and laser-etched branding. Sell to electricians, HVAC techs, and maintenance crews as durable, torque-ready drivers.
Deck/Fence Hardware Upgrades
Specialize in swapping aging lag screws for modern structural 5/16 fasteners on decks and fences. Use impact sockets for speed and consistent torque, provide before/after torque checks, and package by section or post count.
Jig-and-Guide Shop with Socket Bushings
Design and sell 3D-printed drill/driver guides that accept 5/16 deep sockets as wear-resistant bushings. Offer kits that include the socket or BYO, targeting makers who want accurate, repeatable fastener driving without marring heads.
Branded Socket Keychains/Swag
Produce industrial-themed keychains using deep sockets with engraved logos, a short 3/8 square-to-ring adapter, and anodized split rings. Sell as promo swag to auto shops and tool brands or in bulk for event giveaways.

Magnetic Nut-Driver Conversion
Epoxy a small neodymium magnet into the 3/8 in drive end, add a 3/8-to-1/4 hex adapter, and wrap a comfortable handle. You’ll have a compact, magnetized 5/16 nut driver that holds fasteners securely for one-handed starts in tight spaces.
Hidden Key Cache
Recess the socket flush into a bench leg or fence post, secure from the backside, and slip a small magnet inside the well to hold a spare key. Plug the opening with a short 5/16 bolt and washer so it blends in as a normal fastener.
Mini Percussion Shaker
Fill the deep well with a teaspoon of steel shot or BBs, press-fit rubber end caps on both ends (or wrap with heat-shrink), and you’ve got a rugged pocket shaker with a bright metallic tone for jams and classroom rhythm kits.
Leather/Clay Hex Stamp
Mount the socket on a short wooden dowel as a handle and use the hex opening to emboss honeycomb patterns into damp leather or clay. Rotate and overlap impressions for geometric textures on belts, coasters, or tiles.
Industrial Coat Hook
Mount the socket sideways on a wood backer with a screw from behind. The deep well forms a ‘cup’ to catch keyrings and light tools; line the rim with a thin rubber strip to protect items. Make a row of 4–6 for a shop-themed entryway.
