When shopping for construction fasteners and anchors, the choice often comes down to fastener length, pack size, and finish. Sandbaggy offers two countersunk hex-head structural timber screws that look similar at first glance but serve different scopes: the 8-inch Wood Lock Screw listing is priced at $2,058.21, while the 10-Inch Structural Timber Screw pack is priced at $176.60 and includes 200 pieces.
Both fasteners are steel screws with a countersunk hex-head design, and both are aimed at roofing, decking, and framing work where a lag bolt replacement that usually avoids pre-drilling is useful. That shared design is where the similarity ends: length and quantity change the buying decision in a big way.
Quick verdict
If the project calls for 10-inch screws and a 200-piece supply, the 10-inch pack is the more direct choice by listed price. If the project needs an 8-inch structural screw with a galvanized finish, the Wood Lock Screw listing is the one that matches.
Comparison at a glance
| Option | Listed price | Price bar | Highlighted details |
|---|---|---|---|
| Sandbaggy Structural Timber Screws - Countersunk (Hex Head) - Wood Lock Screw | $2,058.21 | 8 in, galvanized, hex drive, 3/16 in screw size | |
| 10-Inch Structural Timber Screws - Countersunk (Hex Head) - Sandbaggy | $176.60 | 10 in, 200 pieces, steel, countersunk hex head |
Where each product wins
The 10-inch Structural Timber Screw pack wins on length and quantity. It gives you a 10-inch fastener and 200 pieces in one listing, and its listed price is $1,881.61 below the other option. That combination makes it the natural answer for a framing task that specifies 10-inch screws and needs a large number of fasteners.
The 8-inch Wood Lock Screw wins when the specified length is 8 inches. It is also the listing that includes galvanized finish, hex drive, and a 3/16-inch screw size in its details. If those specification points are what your framing or decking job requires, the shorter listing has the exact profile.
Final choice by use case
- Need 10-inch fasteners and 200 pieces: go with the 10-Inch Structural Timber Screw pack.
- Need an 8-inch galvanized hex-drive screw: go with the Wood Lock Screw listing.
- Need the lower listed price: the 10-inch pack is listed at $176.60 versus $2,058.21.
Product notes
Sandbaggy Structural Timber Screws - Countersunk (Hex Head) - Wood Lock Screw

This is the shorter of the two listings: an 8-inch countersunk hex-head screw in steel with a galvanized finish, a hex drive, and a 3/16-inch screw size. It is presented for roofing, decking, and framing, and can replace 3/8-inch lag bolts while often avoiding pre-drilling. Pick it when the project requires an 8-inch structural screw and you want the galvanized finish included in the listing. The limitation is the price: at $2,058.21, it carries the higher listed price, and the shorter length will not satisfy a 10-inch fastener spec.
10-Inch Structural Timber Screws - Countersunk (Hex Head) - Sandbaggy

This listing pairs a 10-inch length with a 200-piece quantity and a listed price of $176.60. It shares the Sandbaggy brand, steel material, and countersunk hex-head design with the other option, and it is presented for roofing, decking, and framing. If the work order calls for 10-inch fasteners and you need enough screws for multiple connections, this pack is the one that fits that scope. The trade-off is the pack size: 200 pieces may be more than a small task needs.
