Best 1-3/8-Inch Screws for Cabinets, Drywall, and Wood Projects
The best 1-3/8-inch screw depends on the material and fastening job: choose machine-thread screws for cabinet knobs and pulls, or coarse-thread drywall screws for drywall and wood. The options below include three products in the exact length and two assortments for buyers who also need other screw sizes. Check thread type, head shape, and length before ordering.
| Product | Best For | Length Match |
|---|---|---|
| Bopowo Store #8-32 Machine Screws | Cabinet knobs and pulls | Exact |
| #7 Coarse-Thread Drywall Screws | Drywall and wood | Exact |
| #8 Coarse-Thread Drywall Screws | Drywall, wood, and furniture | Exact |
| FIXLINK Truss Head Assortment | General wood projects | No 1-3/8-inch size listed |
| #4 Stainless Steel Assortment | Small assembly work | No 1-3/8-inch size listed |
Bopowo Store #8-32 Machine Screws
These are #8-32 machine screws measuring 1-3/8 inches long, supplied as a 40-piece set. The product information describes zinc-plated steel and a truss head, with cabinet knobs and pulls as a primary use. Machine threads make this a different screw type from coarse-thread drywall or wood screws.
Best for: Replacing or installing cabinet and drawer hardware when the needed fastener is specifically an 8-32 machine screw of this length. It was selected because it directly matches the requested length and lists furniture, cabinet, and door hardware uses.
Limitation: Avoid this option for ordinary drywall fastening or wood applications that require coarse threads; confirm the hardware’s thread specification first.
#7 Coarse-Thread Drywall Screws
This box contains 175 #7 screws measuring 1-3/8 inches. Listed features include steel construction, a black phosphate coating, coarse threads, Phillips bugle heads, and sharp points. The product is presented for drywall, sheetrock, and wood. Its bugle-head design differs from a flat-head screw, so match the head style to the job.
Best for: Buyers who need an exact-length screw for drywall-to-wood fastening and want a larger quantity. It was selected for its stated 1-3/8-inch length and drywall-oriented features.
Limitation: The listed size is #7, not #8. Check the required screw diameter and drive type before choosing it.
#8 Coarse-Thread Drywall Screws
This 100-piece option lists #8 diameter, a 1-3/8-inch overall length, carbon steel, coarse threads, a black phosphate coating, and a flat head. The sharp point is described for attaching drywall to wood or metal studs. Confirm the intended substrate and head style, especially if the screw needs to sit flush.
Best for: Buyers who need an exact 1-3/8-inch #8 screw with a flat head for drywall or wood-related work. It was selected as a direct-length alternative to the #7 bugle-head option.
Limitation: It is a coarse-thread drywall-style screw, not a machine screw for threaded cabinet hardware.
FIXLINK Truss Head Wood Screw Assortment
This 220-piece assortment includes eight listed lengths: 2, 1-5/8, 1-1/2, 1-1/4, 1, 3/4, 5/8, and 1/2 inches. It is described as a #8 assortment with truss heads and an E-coated finish for furniture and woodworking.
Best for: Woodworkers who need several common lengths in one kit and can use nearby sizes for different tasks. It was included as a broader wood-screw option, not as an exact 1-3/8-inch choice.
Limitation: The listed assortment does not include 1-3/8-inch screws. Do not select it if that exact length is required.
#4 Stainless Steel Flat-Head Assortment
This 600-piece kit contains #4 Phillips flat-head screws made from 304 stainless steel in four short lengths: 1/4, 5/16, 3/8, and 1/2 inch. Its stated uses include furniture, cabinet work, and model assembly.
Best for: Small-scale assembly where short #4 stainless steel screws are appropriate. It was included only as a supplementary assortment for buyers with varied small fastening needs.
Limitation: None of its listed sizes is close to 1-3/8 inches, and its #4 diameter is smaller than the exact-length options.
Buying Guide: How to Choose 1-3/8-Inch Screws
What does 1-3/8 inches describe?
It is the screw’s listed overall length in these product descriptions. Do not assume that a screw with a different head or thread style will work simply because its length matches. Compare the specified diameter, thread, head, and intended material.
Should I choose machine screws or drywall screws?
Choose machine screws for hardware designed to accept machine threads, such as compatible cabinet knobs and pulls. Choose coarse-thread drywall screws for drywall-to-wood fastening or the product’s stated wood applications. These types are not interchangeable by length alone.
Which head style should I check?
Bugle heads, flat heads, and truss heads have different shapes. Match the head to the hardware or surface requirements. The provided product details identify the #7 option as bugle head, the #8 drywall option as flat head, and the machine screws as truss head.
Is an assortment a good choice?
An assortment is useful when the listed lengths suit multiple planned projects. However, neither wood-screw assortment here lists a 1-3/8-inch size. Choose an exact-length product if the screw must measure 1-3/8 inches.
